"value": "AV:L - The malicious input arrives as a `VIRTCHNL_OP_CONFIG_VSI_QUEUES` message on the SR-IOV VF\u2192PF admin-queue mailbox, a PCIe transport, not a network protocol. The attacker needs local control of an assigned VF (guest VM or VF-owning container), so this is local reachability rather than network or adjacent.\nAC:L - The attacker fully controls every input \u2014 `num_tc` and per-TC `count` via ENABLE_CHANNELS, then `num_queue_pairs` and the qpair array via CONFIG_VSI_QUEUES \u2014 so shrinking `num_tc` to leave stale `ch[]` entries and then walking `idx` into them is deterministic on the first attempt with no memory grooming or race. The only precondition, spoofchk disabled, is inherent to any ADq-enabled SR-IOV deployment and is a standard runtime configuration.\nPR:L - The attacker only needs to drive the VF\u0027s admin queue \u2014 kernel/root inside the assigned guest, or possession of the VFIO device \u2014 which is a low-privileged position relative to the host PF driver under attack. No privileges of any kind on the host are required.\nUI:N - The malicious VF sends the virtchnl message sequence entirely on its own initiative. No host administrator or other user action is needed at any stage.\nS:C - The attacking VF sits in a guest VM (or VF-assigned container) while the stale-index read and the resulting hardware queue-context programming occur in the host PF driver\u0027s security authority. The corrupted resources \u2014 HMC LAN Tx/Rx contexts and QTX_CTL bindings of VSIs belonging to the PF or to other VFs \u2014 are outside the attacker\u0027s scope, crossing the guest/host and inter-tenant SR-IOV boundary.\nC:H - Using a stale `ch[idx].vsi_id`, the VF resolves and reprograms the Rx queue context of a VSI it does not own, setting `rx_ctx.base` from its own `dma_ring_addr` so another VSI\u0027s received traffic is DMA\u0027d into attacker-designated memory \u2014 interception of host and cross-guest traffic. On pre-5.2 kernels the same defect additionally reads past the end of `vf-\u003ech[]` into adjacent `struct i40e_vf` state.\nI:H - `i40e_config_vsi_rx_queue()` performs no ownership check and `i40e_config_vsi_tx_queue()` validates only the VF-supplied `info-\u003evsi_id`, so the stale ID lets the VF clear and rewrite the LAN HMC Tx/Rx contexts of a foreign VSI\u0027s queues and issue a `QTX_CTL` write rebinding that PF queue to itself. This is attacker-controlled modification of host- and peer-owned hardware state.\nA:H - Clearing and rewriting queue contexts belonging to the PF\u0027s main VSI or another guest\u0027s VSI stalls or wedges those queues, and out-of-range `pf_queue_id` values (`I40E_QUEUE_END_OF_LIST`) drive HMC operations that trigger adapter error paths, PF/VF reset storms and loss of host networking. The VF can repeat the sequence at will, and a downed host PF takes every guest on the adapter with it."

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scpi: Ensure scpi_info is not assigned if the probe fails
When scpi probe fails, at any point, we need to ensure that the scpi_info
is not set and will remain NULL until the probe succeeds. If it is not
taken care, then it could result use-after-free as the value is exported
via get_scpi_ops() and could refer to a memory allocated via devm_kzalloc()
but freed when the probe fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: core: Harden s32ton() against conversion to 0 bits
Testing by the syzbot fuzzer showed that the HID core gets a
shift-out-of-bounds exception when it tries to convert a 32-bit
quantity to a 0-bit quantity. Ideally this should never occur, but
there are buggy devices and some might have a report field with size
set to zero; we shouldn't reject the report or the device just because
of that.
Instead, harden the s32ton() routine so that it returns a reasonable
result instead of crashing when it is called with the number of bits
set to 0 -- the same as what snto32() does.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Use memcpy() for BIOS version
The strlcat() with FORTIFY support is triggering a panic because it
thinks the target buffer will overflow although the correct target
buffer size is passed in.
Anyway, instead of memset() with 0 followed by a strlcat(), just use
memcpy() and ensure that the resulting buffer is NULL terminated.
BIOSVersion is only used for the lpfc_printf_log() which expects a
properly terminated string.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: sme: cap SSID length in __cfg80211_connect_result()
If the ssid->datalen is more than IEEE80211_MAX_SSID_LEN (32) it would
lead to memory corruption so add some bounds checking.

This is the standard WiFi frame-injection adjacent-network vector.\nAC:L - The attacker fully controls every precondition \u2014 the rogue AP\u0027s per-link beacon contents, the SSID element length (up to 255), the link IDs, and which link is used for association \u2014 and can force (re)association with deauthentication frames. No condition lies outside the attacker\u0027s control.\nPR:N - No credentials or account on the victim system are required; the code runs during association processing on the client, triggered purely by frames the attacker transmits. An open/evil-twin AP suffices.\nUI:N - Association and roaming are performed automatically by the WiFi stack for remembered and open networks, and an attacker can force reassociation with deauth frames, so no deliberate victim action is needed.\nS:U - The corruption is confined to kernel heap memory belonging to the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `wdev-\u003eu.client.ssid_len` is set to the full unclamped datalen, so `nl80211.c:4530` copies up to 223 bytes of adjacent kernel heap out to userspace via NL80211_ATTR_SSID, and the write primitive over BSS pointers enables broader disclosure.\nI:H - An out-of-bounds write of up to 223 fully attacker-controlled bytes overwrites `wdev-\u003elinks[]`, including `client.current_bss` pointers that are later dereferenced and refcount-decremented, yielding a controlled-pointer primitive suitable for control-flow hijacking.\nA:H - Corrupting the `wdev-\u003elinks[]` BSS pointers and surrounding `ieee80211_sub_if_data` state leads to bogus pointer dereferences in `cfg80211_wdev_release_bsses()` and kernel panic; heap overflow reliably crashes the system."

"value": "AV:A - The vulnerable code processes the HCI event stream produced by Bluetooth link activity, and the race is driven by an attacker within Bluetooth radio range who establishes an LE/ACL connection, generates traffic to produce Number of Completed Packets events, and forces host-side connection teardown. Bluetooth is a same-radio-segment vector, not routable, so Adjacent.\nAC:L - The attacker controls both sides of the race \u2014 the traffic that generates completion events and the connect/disconnect churn that drives hci_abort_conn_sync() into hci_conn_del() on the separate req_workqueue \u2014 and can retry indefinitely. The dequeue loop runs up to `count` (0xFFFF) iterations on the freed object, making the window very wide on any SMP system.\nPR:N - An adjacent Bluetooth peer needs no credentials on the target; LE connection establishment requires no pairing or authentication, and the event processing path has no capability check. No local account on the victim is needed at all.\nUI:N - Triggering requires only that the victim\u0027s Bluetooth adapter be up and connectable, which is the default state on phones, laptops, and IoT devices. No victim action is needed.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed hci_conn is read after free, and skb_dequeue() on the freed tx_q returns an attacker-controllable pointer that is then dereferenced through __skb_tstamp_tx()/skb-\u003esk, giving an arbitrary-read primitive over kernel memory once the slab object is reclaimed.\nI:H - The path performs multiple writes into freed memory (conn-\u003esent, comp-\u003eextra, comp-\u003etracked, spinlock and list-head mutation in skb_dequeue) plus a controlled kfree_skb() and an indirect call via sk_error_report(sk), yielding arbitrary write and control-flow hijack potential.\nA:H - The KASAN report shows a slab-use-after-free in the hci_rx_work kernel thread; dereferencing freed/reclaimed memory and looping thousands of times over a stale queue reliably produces an oops or panic, taking down the system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: hfsc: Fix a UAF vulnerability in class handling
This patch fixes a Use-After-Free vulnerability in the HFSC qdisc class
handling. The issue occurs due to a time-of-check/time-of-use condition
in hfsc_change_class() when working with certain child qdiscs like netem
or codel.
The vulnerability works as follows:
1. hfsc_change_class() checks if a class has packets (q.qlen != 0)
2. It then calls qdisc_peek_len(), which for certain qdiscs (e.g.,
codel, netem) might drop packets and empty the queue
3. The code continues assuming the queue is still non-empty, adding
the class to vttree
4. This breaks HFSC scheduler assumptions that only non-empty classes
are in vttree
5. Later, when the class is destroyed, this can lead to a Use-After-Free
The fix adds a second queue length check after qdisc_peek_len() to verify
the queue wasn't emptied.

It then calls qdisc_peek_len(), which for certain qdiscs (e.g.,\n codel, netem) might drop packets and empty the queue\n3. The code continues assuming the queue is still non-empty, adding\n the class to vttree\n4. This breaks HFSC scheduler assumptions that only non-empty classes\n are in vttree\n5.

Per kernel CNA guidance, tc/netlink qdisc bugs are Local.\nAC:L - This is a deterministic time-of-check/time-of-use flaw inside a single netlink operation, not a thread race \u2014 the attacker picks the child qdisc (codel/netem) and its parameters so the peek is guaranteed to drop the packet and empty the queue. No condition outside the attacker\u0027s control is involved, and a reliable reproducer existed.\nPR:L - The tc class paths only check `netlink_ns_capable(skb, net-\u003euser_ns, CAP_NET_ADMIN)`, which an unprivileged user satisfies inside a new user+net namespace (`unshare -Urn`), where they can create a dummy/veth device, build the hfsc hierarchy and generate the traffic. Per guidance, tc/qdisc reachable via user namespaces is Low, not High.\nUI:N - The attacker performs every step \u2014 qdisc/class configuration, packet generation, class change and class deletion \u2014 with no action by any other user. Subsequent dequeue on the attacker\u0027s own device triggers the freed-object access.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own memory and privilege domain; there is no crossing of a VM, IOMMU, or other security-authority boundary. Standard kernel-local privilege escalation is Unchanged.\nC:H - The freed `hfsc_class` remains linked in the parent\u0027s vt_tree/eltree, so `vttree_firstfit()`/`eltree_get_mindl()` read `cl_f`, `cl_vt`, `cl_parent` and `cl-\u003eqdisc` out of reclaimed slab memory, giving an attacker who sprays the slot a controlled read primitive and kernel memory disclosure.\nI:H - The dangling rb_node yields `rb_erase()`/`rb_insert_color()` pointer writes plus the direct `cl-\u003ecl_parent-\u003ecl_cvtmin = cl-\u003ecl_vt` write through freed memory, and `qdisc_dequeue_peeked()` makes an indirect call through `cl-\u003eqdisc-\u003eops-\u003edequeue` read from the freed object \u2014 a full write/control-flow-hijack primitive for privilege escalation.\nA:H - Even without successful exploitation, traversing and erasing rb-tree nodes inside a kfree()d `hfsc_class` reliably corrupts the scheduler tree and panics or oopses the kernel, and the attacker can repeat it at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix use-after-free in cifs_oplock_break
A race condition can occur in cifs_oplock_break() leading to a
use-after-free of the cinode structure when unmounting:
cifs_oplock_break()
_cifsFileInfo_put(cfile)
cifsFileInfo_put_final()
cifs_sb_deactive()
[last ref, start releasing sb]
kill_sb()
kill_anon_super()
generic_shutdown_super()
evict_inodes()
dispose_list()
evict()
destroy_inode()
call_rcu(&inode->i_rcu, i_callback)
spin_lock(&cinode->open_file_lock) <- OK
[later] i_callback()
cifs_free_inode()
kmem_cache_free(cinode)
spin_unlock(&cinode->open_file_lock) <- UAF
cifs_done_oplock_break(cinode) <- UAF
The issue occurs when umount has already released its reference to the
superblock. When _cifsFileInfo_put() calls cifs_sb_deactive(), this
releases the last reference, triggering the immediate cleanup of all
inodes under RCU. However, cifs_oplock_break() continues to access the
cinode after this point, resulting in use-after-free.
Fix this by holding an extra reference to the superblock during the
entire oplock break operation. This ensures that the superblock and
its inodes remain valid until the oplock break completes.

A malicious, compromised, or on-path SMB server (signing is frequently absent) reaches this over the network or WAN.\nAC:L - This is not a tight race: the attacker parks the worker indefinitely by refusing to complete writeback, so whenever the unmount lands the worker deterministically holds the last superblock reference, and it then releases the stall at a time of its choosing. The intervening `kill_sb` network round trips guarantee the RCU grace period elapses before `cifs_done_oplock_break(cinode)`, making the use-after-free reliable and infinitely repeatable.\nPR:N - The attacker is the remote SMB server or an on-path attacker and holds no credentials, account, or capability on the victim client; oplock/lease breaks are unsolicited server-to-client notifications handled by the demultiplex thread. Client-side mount configuration is a deployment condition, not an attacker privilege.\nUI:N - The CIFS mount is a standing deployment condition (fstab/autofs/systemd `.automount`/pam_mount), and the required unmount happens automatically on idle expiry, logout, or attacker-induced link loss \u2014 no person participates. Because the attacker can hold the oplock-break worker parked indefinitely, it need only wait for that automatic teardown rather than race any user action.\nS:U - The use-after-free corrupts kernel slab memory (`cifs_inode_cache`) within the same kernel security authority as the vulnerable CIFS client code. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - When the freed `openFileList` head is groomed to appear non-empty, `smb2_oplock_response()` reads `cinode-\u003elease_key` out of freed slab memory and transmits it to the attacker\u0027s server in the break acknowledgement \u2014 a repeatable kernel-heap infoleak \u2014 and dereferences `cinode-\u003enetfs.inode.i_sb-\u003es_fs_info` from the dead object. Controlling the reallocated object escalates this to arbitrary kernel memory disclosure.\nI:H - `spin_unlock(\u0026cinode-\u003eopen_file_lock)` and `cifs_done_oplock_break()`\u0027s `clear_bit(CIFS_INODE_PENDING_OPLOCK_BREAK, \u0026cinode-\u003eflags)` are out-of-lifetime writes at fixed offsets into whatever object reclaims the freed `cifsInodeInfo`, and the attacker can refill that slab with inodes whose fields come from its own server responses. Combined with the wild `i_sb-\u003es_fs_info` dereference, this is the standard heap-grooming path to a write primitive and control-flow hijack.\nA:H - Operating on the freed `cifsInodeInfo` \u2014 spinlock manipulation, list traversal, and a bit clear on released slab memory \u2014 produces KASAN splats, slab corruption, and oops/panic, as reported in kernel.org bugzilla #220309.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/gem: Acquire references on GEM handles for framebuffers
A GEM handle can be released while the GEM buffer object is attached
to a DRM framebuffer. This leads to the release of the dma-buf backing
the buffer object, if any. [1] Trying to use the framebuffer in further
mode-setting operations leads to a segmentation fault. Most easily
happens with driver that use shadow planes for vmap-ing the dma-buf
during a page flip. An example is shown below.

Acquiring GEM handles for the framebuffer's GEM buffer objects prevents
this from happening. The framebuffer's cleanup later puts the handle
references.
Commit 1a148af06000 ("drm/gem-shmem: Use dma_buf from GEM object
instance") triggers the segmentation fault easily by using the dma-buf
field more widely. The underlying issue with reference counting has
been present before.
v2:
- acquire the handle instead of the BO (Christian)
- fix comment style (Christian)
- drop the Fixes tag (Christian)
- rename err_ gotos
- add missing Link tag

Where a window is involved (begin_fb_access in prepare_planes vs. end_fb_access in cleanup_planes), the attacker drives both sides from their own threads.\nPR:L - Only an unprivileged local account with access to a DRM primary node is needed (video group, active-seat ACL, Android graphics group); ADDFB2/RMFB/GEM_CLOSE require no master or auth flags at all. DRM master, needed for the atomic commit, is handed out by drm_master_open() to the first opener of the node with no capability check, and is also available via DRM leases \u2014 no real root is required.\nUI:N - A single attacker-controlled process performs every step \u2014 buffer import, framebuffer creation, handle close, and the mode-setting commit.

Such premature release of a GEM/dma-buf backing store, with attacker-controlled heap grooming via DUMB_CREATE and repeated import/close cycles, is leverageable into disclosure of reallocated kernel memory contents.\nI:H - The same missing handle reference lets the kernel continue writing through stale framebuffer state (shadow-plane blits, damage handling) into storage whose backing reference has been dropped, and the unguarded dma_buf_end_cpu_access() path performs an indirect call through dmabuf-\u003eops on a released/invalid dma_buf. This gives a memory-corruption and control-flow primitive rather than a benign failure.\nA:H - The documented result is a WARNING splat in dma_buf_vmap() (a panic on the widely deployed panic_on_warn configurations) and a kernel oops \u2014 dma_buf_end_cpu_access() only does WARN_ON(!dmabuf) without returning and then dereferences dmabuf-\u003eresv and dmabuf-\u003eops. Any local user with DRM access can trigger this repeatedly to crash the machine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Don't BUG if userspace injects an interrupt with GIF=0
Don't BUG/WARN on interrupt injection due to GIF being cleared,
since it's trivial for userspace to force the situation via
KVM_SET_VCPU_EVENTS (even if having at least a WARN there would be correct
for KVM internally generated injections).

The timing oracle additionally recovers secret-key-derived MAC values.\nI:H - A recovered MAC makes the kernel accept attacker-crafted segment lists as authentic, allowing arbitrary rewriting of forwarding paths and injection of spoofed traffic into tenant networks and internal L2 bridges \u2014 a complete authentication bypass of the SRv6 integrity mechanism.\nA:H - Forged segment lists can be built to loop packets repeatedly between SR nodes and to blackhole or misdirect legitimate traffic, disrupting forwarding for the node and the SR domain it serves."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Validate UAC3 cluster segment descriptors
UAC3 class segment descriptors need to be verified whether their sizes
match with the declared lengths and whether they fit with the
allocated buffer sizes, too. Otherwise malicious firmware may lead to
the unexpected OOB accesses.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/iwcm: Fix use-after-free of work objects after cm_id destruction
The commit 59c68ac31e15 ("iw_cm: free cm_id resources on the last
deref") simplified cm_id resource management by freeing cm_id once all
references to the cm_id were removed. The references are removed either
upon completion of iw_cm event handlers or when the application destroys
the cm_id. This commit introduced the use-after-free condition where
cm_id_private object could still be in use by event handler works during
the destruction of cm_id. The commit aee2424246f9 ("RDMA/iwcm: Fix a
use-after-free related to destroying CM IDs") addressed this use-after-
free by flushing all pending works at the cm_id destruction.
However, still another use-after-free possibility remained. It happens
with the work objects allocated for each cm_id_priv within
alloc_work_entries() during cm_id creation, and subsequently freed in
dealloc_work_entries() once all references to the cm_id are removed.
If the cm_id's last reference is decremented in the event handler work,
the work object for the work itself gets removed, and causes the use-
after-free BUG below:

This BUG is reproducible by repeating the blktests test case nvme/061
for the rdma transport and the siw driver.
To avoid the use-after-free of cm_id_private work objects, ensure that
the last reference to the cm_id is decremented not in the event handler
works, but in the cm_id destruction context. For that purpose, mo

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/iwcm: Fix use-after-free of work objects after cm_id destruction\n\nThe commit 59c68ac31e15 (\"iw_cm: free cm_id resources on the last\nderef\") simplified cm_id resource management by freeing cm_id once all\nreferences to the cm_id were removed. The references are removed either\nupon completion of iw_cm event handlers or when the application destroys\nthe cm_id. This commit introduced the use-after-free condition where\ncm_id_private object could still be in use by event handler works during\nthe destruction of cm_id. The commit aee2424246f9 (\"RDMA/iwcm: Fix a\nuse-after-free related to destroying CM IDs\") addressed this use-after-\nfree by flushing all pending works at the cm_id destruction.\n\nHowever, still another use-after-free possibility remained. It happens\nwith the work objects allocated for each cm_id_priv within\nalloc_work_entries() during cm_id creation, and subsequently freed in\ndealloc_work_entries() once all references to the cm_id are removed.\nIf the cm_id\u0027s last reference is decremented in the event handler work,\nthe work object for the work itself gets removed, and causes the use-\nafter-free BUG below:\n\n BUG: KASAN: slab-use-after-free in __pwq_activate_work+0x1ff/0x250\n Read of size 8 at addr ffff88811f9cf800 by task kworker/u16:1/147091\n\n CPU: 2 UID: 0 PID: 147091 Comm: kworker/u16:1 Not tainted 6.15.0-rc2+ #27 PREEMPT(voluntary)\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-3.fc41 04/01/2014\n Workqueue: 0x0 (iw_cm_wq)\n Call Trace:\n \u003cTASK\u003e\n dump_stack_lvl+0x6a/0x90\n print_report+0x174/0x554\n ? __virt_addr_valid+0x208/0x430\n ? __pwq_activate_work+0x1ff/0x250\n kasan_report+0xae/0x170\n ? __pwq_activate_work+0x1ff/0x250\n __pwq_activate_work+0x1ff/0x250\n pwq_dec_nr_in_flight+0x8c5/0xfb0\n process_one_work+0xc11/0x1460\n ? __pfx_process_one_work+0x10/0x10\n ? assign_work+0x16c/0x240\n worker_thread+0x5ef/0xfd0\n ? __pfx_worker_thread+0x10/0x10\n kthread+0x3b0/0x770\n ? __pfx_kthread+0x10/0x10\n ? rcu_is_watching+0x11/0xb0\n ? _raw_spin_unlock_irq+0x24/0x50\n ? rcu_is_watching+0x11/0xb0\n ? __pfx_kthread+0x10/0x10\n ret_from_fork+0x30/0x70\n ? __pfx_kthread+0x10/0x10\n ret_from_fork_asm+0x1a/0x30\n \u003c/TASK\u003e\n\n Allocated by task 147416:\n kasan_save_stack+0x2c/0x50\n kasan_save_track+0x10/0x30\n __kasan_kmalloc+0xa6/0xb0\n alloc_work_entries+0xa9/0x260 [iw_cm]\n iw_cm_connect+0x23/0x4a0 [iw_cm]\n rdma_connect_locked+0xbfd/0x1920 [rdma_cm]\n nvme_rdma_cm_handler+0x8e5/0x1b60 [nvme_rdma]\n cma_cm_event_handler+0xae/0x320 [rdma_cm]\n cma_work_handler+0x106/0x1b0 [rdma_cm]\n process_one_work+0x84f/0x1460\n worker_thread+0x5ef/0xfd0\n kthread+0x3b0/0x770\n ret_from_fork+0x30/0x70\n ret_from_fork_asm+0x1a/0x30\n\n Freed by task 147091:\n kasan_save_stack+0x2c/0x50\n kasan_save_track+0x10/0x30\n kasan_save_free_info+0x37/0x60\n __kasan_slab_free+0x4b/0x70\n kfree+0x13a/0x4b0\n dealloc_work_entries+0x125/0x1f0 [iw_cm]\n iwcm_deref_id+0x6f/0xa0 [iw_cm]\n cm_work_handler+0x136/0x1ba0 [iw_cm]\n process_one_work+0x84f/0x1460\n worker_thread+0x5ef/0xfd0\n kthread+0x3b0/0x770\n ret_from_fork+0x30/0x70\n ret_from_fork_asm+0x1a/0x30\n\n Last potentially related work creation:\n kasan_save_stack+0x2c/0x50\n kasan_record_aux_stack+0xa3/0xb0\n __queue_work+0x2ff/0x1390\n queue_work_on+0x67/0xc0\n cm_event_handler+0x46a/0x820 [iw_cm]\n siw_cm_upcall+0x330/0x650 [siw]\n siw_cm_work_handler+0x6b9/0x2b20 [siw]\n process_one_work+0x84f/0x1460\n worker_thread+0x5ef/0xfd0\n kthread+0x3b0/0x770\n ret_from_fork+0x30/0x70\n ret_from_fork_asm+0x1a/0x30\n\nThis BUG is reproducible by repeating the blktests test case nvme/061\nfor the rdma transport and the siw driver.\n\nTo avoid the use-after-free of cm_id_private work objects, ensure that\nthe last reference to the cm_id is decremented not in the event handler\nworks, but in the cm_id destruction context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: make sure to abort the stream if headers are bogus
Normally we wait for the socket to buffer up the whole record
before we service it. If the socket has a tiny buffer, however,
we read out the data sooner, to prevent connection stalls.
Make sure that we abort the connection when we find out late
that the record is actually invalid. Retrying the parsing is
fine in itself but since we copy some more data each time
before we parse we can overflow the allocated skb space.
Constructing a scenario in which we're under pressure without
enough data in the socket to parse the length upfront is quite
hard. syzbot figured out a way to do this by serving us the header
in small OOB sends, and then filling in the recvbuf with a large
normal send.
Make sure that tls_rx_msg_size() aborts strp, if we reach
an invalid record there's really no way to recover.

Summary
In the Linux kernel, the following vulnerability has been resolved:
of_numa: fix uninitialized memory nodes causing kernel panic
When there are memory-only nodes (nodes without CPUs), these nodes are not
properly initialized, causing kernel panic during boot.
of_numa_init
of_numa_parse_cpu_nodes
node_set(nid, numa_nodes_parsed);
of_numa_parse_memory_nodes
In of_numa_parse_cpu_nodes, numa_nodes_parsed gets updated only for nodes
containing CPUs. Memory-only nodes should have been updated in
of_numa_parse_memory_nodes, but they weren't.
Subsequently, when free_area_init() attempts to access NODE_DATA() for
these uninitialized memory nodes, the kernel panics due to NULL pointer
dereference.
This can be reproduced on ARM64 QEMU with 1 CPU and 2 memory nodes:
qemu-system-aarch64 \
-cpu host -nographic \
-m 4G -smp 1 \
-machine virt,accel=kvm,gic-version=3,iommu=smmuv3 \
-object memory-backend-ram,size=2G,id=mem0 \
-object memory-backend-ram,size=2G,id=mem1 \
-numa node,nodeid=0,memdev=mem0 \
-numa node,nodeid=1,memdev=mem1 \
-kernel $IMAGE \
-hda $DISK \
-append "console=ttyAMA0 root=/dev/vda rw earlycon"

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSY
Since commit 8f4f68e788c3 ("crypto: pcrypt - Fix hungtask for
PADATA_RESET"), the pcrypt encryption and decryption operations return
-EAGAIN when the CPU goes online or offline. In alg_test(), a WARN is
generated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns
-EAGAIN, the unnecessary panic will occur when panic_on_warn set 1.
Fix this issue by calling crypto layer directly without parallelization
in that case.

Currently, ep_loop_check_proc() ensures that the graph is loop-free and
does some recursion depth checks, but those recursion depth checks don't
limit the depth of the resulting tree for two reasons:
- They don't look upwards in the tree.
- If there are multiple downwards paths of different lengths, only one of
the paths is actually considered for the depth check since commit
28d82dc1c4ed ("epoll: limit paths").
Essentially, the current recursion depth check in ep_loop_check_proc() just
serves to prevent it from recursing too deeply while checking for loops.
A more thorough check is done in reverse_path_check() after the new graph
edge has already been created; this checks, among other things, that no
paths going upwards from any non-epoll file with a length of more than 5
edges exist. However, this check does not apply to non-epoll files.
As a result, it is possible to recurse to a depth of at least roughly 500,
tested on v6.15. (I am unsure if deeper recursion is possible; and this may
have changed with commit 8c44dac8add7 ("eventpoll: Fix priority inversion
problem").)
To fix it:
1. In ep_loop_check_proc(), note the subtree depth of each visited node,
and use subtree depths for the total depth calculation even when a subtree
has already been visited.
2. Add ep_get_upwards_depth_proc() for similarly determining the maximum
depth of an upwards walk.
3. In ep_loop_check(), use these values to limit the total path length
between epoll nodes to EP_MAX_NESTS edges.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kernfs: Fix UAF in polling when open file is released
A use-after-free (UAF) vulnerability was identified in the PSI (Pressure
Stall Information) monitoring mechanism:
BUG: KASAN: slab-use-after-free in psi_trigger_poll+0x3c/0x140
Read of size 8 at addr ffff3de3d50bd308 by task systemd/1
psi_trigger_poll+0x3c/0x140

cgroup_file_show+0x150/0x268
cgroup_pressure_write+0x1dc/0x340
cgroup_file_write+0x274/0x548
Reproduction Steps:
1. Open test/cpu.pressure and establish epoll monitoring
2. Disable monitoring: echo 0 > test/cgroup.pressure
3. Re-enable monitoring: echo 1 > test/cgroup.pressure
The race condition occurs because:
1. When cgroup.pressure is disabled (echo 0 > cgroup.pressure), it:
- Releases PSI triggers via cgroup_file_release()
- Frees of->priv through kernfs_drain_open_files()
2. While epoll still holds reference to the file and continues polling
3. Re-enabling (echo 1 > cgroup.pressure) accesses freed of->priv
epolling disable/enable cgroup.pressure
fd=open(cpu.pressure)
while(1)
...
epoll_wait
kernfs_fop_poll
kernfs_get_active = true echo 0 > cgroup.pressure
... cgroup_file_show
kernfs_show
// inactive kn
kernfs_drain_open_files
cft->release(of);
kfree(ctx);
...
kernfs_get_active = false
echo 1 > cgroup.pressure
kernfs_show
kernfs_activate_one(kn);
kernfs_fop_poll
kernfs_get_active = true
cgroup_file_poll
psi_trigger_poll
// UAF
...
end: close(fd)
To address this issue, introduce kernfs_get_active_of() for kernfs open
files to obtain active references. This function will fail if the open file
has been released. Replace kernfs_get_active() with kernfs_get_active_of()
to prevent further operations on released file descriptors.

There is no network-facing path to `kernfs_fop_poll()`/`cgroup_pressure_write()`.\nAC:L - The reproduction is a deterministic three-step sequence (open+epoll, `echo 0 \u003e cgroup.pressure`, `echo 1 \u003e cgroup.pressure`) fully driven by the attacker, with no timing window to win. The gap between the `kfree()` and the re-activated poll is attacker-controlled and arbitrarily long, allowing reliable heap spraying of the kmalloc-192 slot.\nPR:L - An unprivileged local user suffices: `cgroup_add_file()` stamps created cgroup files with `current_fsuid()`, so any user with a delegated subtree (systemd `user@$UID.service`, containers, rootless podman) owns and can write both `cgroup.pressure` and `cpu.pressure` in a cgroup they `mkdir`. No capability check exists on this path, and cgroup2 is `FS_USERNS_MOUNT`.\nUI:N - The attacker performs the poll and both `cgroup.pressure` writes itself; no victim action is needed. (A privileged poller such as systemd/systemd-oomd can additionally be victimized, but that is not required.)\nS:U - The freed object, the corrupting write, and the resulting compromise all live in the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The stale `of-\u003epriv` yields an attacker-controlled `struct psi_trigger *` in `psi_trigger_poll()`, and the subsequent `t-\u003eof` / `of_on(of)` / `atomic_read(\u0026on-\u003eevent)` dereferences turn that into an arbitrary kernel-memory read primitive, disclosing sensitive kernel data.\nI:H - `poll_wait()` on the forged `t-\u003eevent_wait` inserts a wait-queue entry at an attacker-chosen address (arbitrary linked-list write), `cmpxchg(\u0026t-\u003eevent, 1, 0)` adds a conditional write, and the eventual `wake_up()` calls a `wait_queue_entry-\u003efunc` pointer from corrupted memory \u2014 a viable control-flow hijack and local privilege escalation.\nA:H - Even without exploitation the use-after-free reliably produces a KASAN slab-use-after-free / oops on a wild pointer dereference, and a failed spray attempt panics the kernel \u2014 a full denial of service triggerable at will by an unprivileged user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
efivarfs: Fix slab-out-of-bounds in efivarfs_d_compare
Observed on kernel 6.6 (present on master as well):
BUG: KASAN: slab-out-of-bounds in memcmp+0x98/0xd0
Call trace:
kasan_check_range+0xe8/0x190
__asan_loadN+0x1c/0x28
memcmp+0x98/0xd0
efivarfs_d_compare+0x68/0xd8
__d_lookup_rcu_op_compare+0x178/0x218
__d_lookup_rcu+0x1f8/0x228
d_alloc_parallel+0x150/0x648

do_filp_open+0x114/0x248
do_sys_openat2+0x340/0x3c0
__arm64_sys_openat+0x120/0x1a0
If dentry->d_name.len < EFI_VARIABLE_GUID_LEN , 'guid' can become
negative, leadings to oob. The issue can be triggered by parallel
lookups using invalid filename:
T1 T2
lookup_open
->lookup
simple_lookup
d_add
// invalid dentry is added to hash list
lookup_open
d_alloc_parallel
__d_lookup_rcu
__d_lookup_rcu_op_compare
hlist_bl_for_each_entry_rcu
// invalid dentry can be retrieved
->d_compare
efivarfs_d_compare
// oob
Fix it by checking 'guid' before cmp.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock/virtio: Validate length in packet header before skb_put()
When receiving a vsock packet in the guest, only the virtqueue buffer
size is validated prior to virtio_vsock_skb_rx_put(). Unfortunately,
virtio_vsock_skb_rx_put() uses the length from the packet header as the
length argument to skb_put(), potentially resulting in SKB overflow if
the host has gone wonky.
Validate the length as advertised by the packet header before calling
virtio_vsock_skb_rx_put().

Every trigger condition is fully under the attacker\u0027s control.\nPR:N - No privileges exist in the vulnerable component \u2014 the guest kernel \u2014 for the attacker to hold; virtio_transport_rx_work() consumes the buffer from a workqueue as soon as the device completes it, with no guest socket, user, or capability involved. Userspace VMMs (Firecracker, crosvm, vhost-user-vsock) are deliberately deprivileged, and under SEV-SNP/TDX/CCA the host is untrusted by design.\nUI:N - The RX work item processes the malicious buffer automatically on device completion, and the vsockmon tap path runs before any socket lookup. No guest user opens a socket, reads data, or performs any action.\nS:U - The vulnerable component and every impacted resource are the guest kernel and its own userspace, which share one security authority.

Repeatable per packet with heap grooming, this is an arbitrary kernel-memory read.\nI:H - The wraparound bypasses skb_over_panic() and leaves a corrupted skb whose len/tail are desynchronized from the allocation; virtio_transport_build_skb() then truncates the size_t allocation size to 75 bytes and performs skb_put_data() of 0xFFFFFFFF, an unbounded out-of-bounds memcpy write out of a small slab object. Combined with the read primitive this is a heap-corruption primitive suitable for control-flow hijack in the guest.\nA:H - Any header len outside the narrow wrap window drives skb-\u003etail past skb-\u003eend, hitting skb_over_panic() \u2192 BUG() in the virtio_vsock workqueue, and the wrap path instead faults on a multi-gigabyte copy. Either way the guest kernel oopses or panics, triggerable at will and repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86/hyper-v: Skip non-canonical addresses during PV TLB flush
In KVM guests with Hyper-V hypercalls enabled, the hypercalls
HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST and HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST_EX
allow a guest to request invalidation of portions of a virtual TLB.
For this, the hypercall parameter includes a list of GVAs that are supposed
to be invalidated.
However, when non-canonical GVAs are passed, there is currently no
filtering in place and they are eventually passed to checked invocations of
INVVPID on Intel / INVLPGA on AMD. While AMD's INVLPGA silently ignores
non-canonical addresses (effectively a no-op), Intel's INVVPID explicitly
signals VM-Fail and ultimately triggers the WARN_ONCE in invvpid_error():
invvpid failed: ext=0x0 vpid=1 gva=0xaaaaaaaaaaaaa000
WARNING: CPU: 6 PID: 326 at arch/x86/kvm/vmx/vmx.c:482
invvpid_error+0x91/0xa0 [kvm_intel]
Modules linked in: kvm_intel kvm 9pnet_virtio irqbypass fuse
CPU: 6 UID: 0 PID: 326 Comm: kvm-vm Not tainted 6.15.0 #14 PREEMPT(voluntary)

kvm_hv_vcpu_flush_tlb+0x24f/0x4f0 [kvm]
kvm_arch_vcpu_ioctl_run+0x3013/0x5810 [kvm]
Hyper-V documents that invalid GVAs (those that are beyond a partition's
GVA space) are to be ignored. While not completely clear whether this
ruling also applies to non-canonical GVAs, it is likely fine to make that
assumption, and manual testing on Azure confirms "real" Hyper-V interprets
the specification in the same way.
Skip non-canonical GVAs when processing the list of address to avoid
tripping the INVVPID failure. Alternatively, KVM could filter out "bad"
GVAs before inserting into the FIFO, but practically speaking the only
downside of pushing validation to the final processing is that doing so
is suboptimal for the guest, and no well-behaved guest will request TLB
flushes for non-canonical addresses.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: separate no-async decryption request handling from async
If we're not doing async, the handling is much simpler. There's no
reference counting, we just need to wait for the completion to wake us
up and return its result.
We should preferably also use a separate crypto_wait. I'm not seeing a
UAF as I did in the past, I think aec7961916f3 ("tls: fix race between
async notify and socket close") took care of it.
This will make the next fix easier.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb: fix huge_pmd_unshare() vs GUP-fast race
huge_pmd_unshare() drops a reference on a page table that may have
previously been shared across processes, potentially turning it into a
normal page table used in another process in which unrelated VMAs can
afterwards be installed.
If this happens in the middle of a concurrent gup_fast(), gup_fast() could
end up walking the page tables of another process. While I don't see any
way in which that immediately leads to kernel memory corruption, it is
really weird and unexpected.
Fix it with an explicit broadcast IPI through tlb_remove_table_sync_one(),
just like we do in khugepaged when removing page tables for a THP
collapse.

"value": "AV:L - The race is driven entirely through local syscalls \u2014 a PUD-aligned MAP_SHARED hugetlbfs/MAP_HUGETLB mapping plus munmap/mremap/mprotect/fallocate to trigger huge_pmd_unshare(), raced against gup_fast() reached via O_DIRECT, io_uring registered buffers or vmsplice. There is no network-facing path into mm/hugetlb.c.\nAC:L - The attacker controls every participant: one thread issues the GUP-fast pin, a sibling thread issues the unmap that calls huge_pmd_unshare(), and a second attacker process reuses the now-exclusively-owned PMD table, and the whole sequence can be looped indefinitely. The gup_fast() IRQ-disabled window can additionally be widened by requesting a full PUD-sized pin range, since the PUD is latched once at the start of gup_fast_pud_range() while the PMD loop then walks 512 entries.\nPR:L - hugetlb_file_setup() performs no capable() check for MAP_HUGETLB anonymous mappings, and none of huge_pmd_unshare()\u0027s callers or the GUP-fast entry points require any capability, so an ordinary local user account suffices. Only a configured hugepage pool is needed, which is standard on cloud, virtualization, DPDK and database hosts.\nUI:N - Exploitation is fully self-contained \u2014 the attacker forks its own second process to establish PMD sharing and to repurpose the unshared page table. No victim action is required at any point.\nS:U - The defect and its impact are both within the kernel\u0027s own memory-management security authority, with no VM, IOMMU or sandbox boundary crossed. This is a standard kernel memory-safety/privilege-escalation shape, so scope remains Unchanged.\nC:H - A gup_fast() walker that latched the stale PUD proceeds to walk a PMD table that now backs a different process\u0027s address space, pinning and returning struct pages that belong to that other mm. Handing those pages to O_DIRECT or vmsplice yields a direct read primitive against another process\u0027s memory, which on hosts where a hugetlbfs segment is shared across trust boundaries (QEMU/vhost-user, DPDK/SPDK, shared DB segments) discloses privileged data.\nI:H - The same stale walk with FOLL_WRITE returns writable pins on pages mapped by the foreign address space, so an O_DIRECT read or io_uring write into that buffer modifies another process\u0027s memory arbitrarily. It also leaves DMA pins and page reference/mapcount state established behind the back of the owning mm, corrupting page-table and pinning invariants the kernel relies on.\nA:H - GUP-fast traversing page tables of an unrelated address space while that process is concurrently tearing down and re-populating them is exactly the unsynchronized page-table access the kernel elsewhere prevents with tlb_remove_table_sync_one(), and it readily produces inconsistent refcount/mapcount state, VM_WARN/BUG trips, and oops in mm paths. The race can be re-armed in a loop by an unprivileged process."

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: linearize cloned gso packets in sctp_rcv
A cloned head skb still shares these frag skbs in fraglist with the
original head skb. It's not safe to access these frag skbs.
syzbot reported two use-of-uninitialized-memory bugs caused by this:

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: fix use-after-free in cmp_bss()
Following bss_free() quirk introduced in commit 776b3580178f
("cfg80211: track hidden SSID networks properly"), adjust
cfg80211_update_known_bss() to free the last beacon frame
elements only if they're not shared via the corresponding
'hidden_beacon_bss' pointer.

Per kernel guidance, WiFi frame injection is Adjacent.\nAC:L - The attacker controls every precondition: SSID hiding, BSSID, the two channels, the beacon/probe-response pairs that build the hidden groups, and the CSA that fires `cfg80211_update_assoc_bss_entry()`; the victim\u0027s routine background scans supply the rest without attacker effort. The freed object\u0027s size is attacker-chosen via IE length, so heap grooming is also under attacker control.\nPR:N - No credentials or account on the target system are needed; beacons, probe responses and public action frames are unauthenticated and unprotected (beacon protection/BIGTK is rarely deployed), so a rogue AP or frame injector reaches the code with zero privileges.\nUI:N - Scanning, beacon processing and CSA handling are performed automatically by the kernel for an associated STA \u2014 no user action is required, and the attacker can spoof the legitimate AP\u0027s frames against an already-connected victim.\nS:U - The freed `cfg80211_bss_ies` allocation and all corrupted state live in the kernel\u0027s own slab and cfg80211 BSS list; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The stale `beacon_ies`/`ies` pointers are read by `cmp_bss()` and, critically, copied wholesale to userspace via `NL80211_BSS_BEACON_IES` in scan dumps, disclosing reallocated freed heap contents \u2014 and an attacker-controlled `len` after reallocation extends this to a large out-of-bounds kernel memory read.\nI:H - The shared IEs are freed while still owned by the beacon BSS, so the later `bss_free()` performs a second `kfree_rcu()` on the same object \u2014 a double free of an attacker-sized allocation, a well-established primitive for arbitrary write and control-flow hijack; freed-memory contents also drive rb-tree ordering decisions.\nA:H - Use-after-free reads in `cmp_bss()` plus the subsequent double free corrupt the slab allocator and reliably produce oopses/panics, and the condition can be re-triggered at will by an in-range attacker."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: Fix UAF in hci_acl_create_conn_sync
This fixes the following UFA in hci_acl_create_conn_sync where a
connection still pending is command submission (conn->state == BT_OPEN)
maybe freed, also since this also can happen with the likes of

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: don't ignore the return code of svc_proc_register()
Currently, nfsd_proc_stat_init() ignores the return value of
svc_proc_register(). If the procfile creation fails, then the kernel
will WARN when it tries to remove the entry later.
Fix nfsd_proc_stat_init() to return the same type of pointer as
svc_proc_register(), and fix up nfsd_net_init() to check that and fail
the nfsd_net construction if it occurs.
svc_proc_register() can fail if the dentry can't be allocated, or if an
identical dentry already exists. The second case is pretty unlikely in
the nfsd_net construction codepath, so if this happens, return -ENOMEM.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: sch_qfq: Fix race condition on qfq_aggregate
A race condition can occur when 'agg' is modified in qfq_change_agg
(called during qfq_enqueue) while other threads access it
concurrently. For example, qfq_dump_class may trigger a NULL
dereference, and qfq_delete_class may cause a use-after-free.
This patch addresses the issue by:
1. Moved qfq_destroy_class into the critical section.
2. Added sch_tree_lock protection to qfq_dump_class and
qfq_dump_class_stats.

No victim action is needed.\nS:U - The corruption is confined to kernel heap objects within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - qfq_dump_class()/qfq_dump_class_stats() read class_weight and lmax from an already-freed qfq_aggregate and copy them to userspace via netlink, and the broader use-after-free on a generic kmalloc slab object can be groomed into an arbitrary kernel-memory read primitive.\nI:H - The unlocked qfq_rm_from_agg()/qfq_update_agg()/qfq_destroy_agg() in qfq_delete_class() write into a concurrently freed aggregate (list unlink plus several field stores) and can double-free it, giving heap-spray-based write primitives suitable for control-flow hijack and privilege escalation.\nA:H - The race trivially produces a NULL pointer dereference on cl-\u003eagg, a use-after-free oops, a double free, or a divide-by-zero from corrupted num_classes/wsum, any of which panics the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: fix the 'para' buffer size to avoid reading out of bounds
Set the size to 6 instead of 2, since 'para' array is passed to
'rtw_fw_bt_wifi_control(rtwdev, para[0], ¶[1])', which reads
5 bytes:
void rtw_fw_bt_wifi_control(struct rtw_dev *rtwdev, u8 op_code, u8 *data)
{
...
SET_BT_WIFI_CONTROL_DATA1(h2c_pkt, *data);
SET_BT_WIFI_CONTROL_DATA2(h2c_pkt, *(data + 1));
...
SET_BT_WIFI_CONTROL_DATA5(h2c_pkt, *(data + 4));
Detected using the static analysis tool - Svace.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: bcd2000: Fix a UAF bug on the error path of probing
When the driver fails in snd_card_register() at probe time, it will free
the 'bcd2k->midi_out_urb' before killing it, which may cause a UAF bug.
The following log can reveal it:
[ 50.727020] BUG: KASAN: use-after-free in bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000]
[ 50.727623] Read of size 8 at addr ffff88810fab0e88 by task swapper/4/0
[ 50.729530] Call Trace:
[ 50.732899] bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000]
Fix this by adding usb_kill_urb() before usb_free_urb().

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/vmscape: Add conditional IBPB mitigation
VMSCAPE is a vulnerability that exploits insufficient branch predictor
isolation between a guest and a userspace hypervisor (like QEMU). Existing
mitigations already protect kernel/KVM from a malicious guest. Userspace
can additionally be protected by flushing the branch predictors after a
VMexit.
Since it is the userspace that consumes the poisoned branch predictors,
conditionally issue an IBPB after a VMexit and before returning to
userspace. Workloads that frequently switch between hypervisor and
userspace will incur the most overhead from the new IBPB.
This new IBPB is not integrated with the existing IBPB sites. For
instance, a task can use the existing speculation control prctl() to
get an IBPB at context switch time. With this implementation, the
IBPB is doubled up: one at context switch and another before running
userspace.
The intent is to integrate and optimize these cases post-embargo.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: xts - Handle EBUSY correctly
As it is xts only handles the special return value of EINPROGRESS,
which means that in all other cases it will free data related to the
request.
However, as the caller of xts may specify MAY_BACKLOG, we also need
to expect EBUSY and treat it in the same way. Otherwise backlogged
requests will trigger a use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix a race when updating an existing write
After nfs_lock_and_join_requests() tests for whether the request is
still attached to the mapping, nothing prevents a call to
nfs_inode_remove_request() from succeeding until we actually lock the
page group.
The reason is that whoever called nfs_inode_remove_request() doesn't
necessarily have a lock on the page group head.
So in order to avoid races, let's take the page group lock earlier in
nfs_lock_and_join_requests(), and hold it across the removal of the
request in nfs_inode_remove_request().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: smsc75xx: Limit packet length to skb->len
Packet length retrieved from skb data may be larger than
the actual socket buffer length (up to 9026 bytes). In such
case the cloned skb passed up the network stack will leak
kernel memory contents.

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/waitid: always prune wait queue entry in io_waitid_wait()
For a successful return, always remove our entry from the wait queue
entry list. Previously this was skipped if a cancelation was in
progress, but this can race with another invocation of the wait queue
entry callback.

"value": "AV:L - The vulnerability is reached through the io_uring syscall interface (`io_uring_setup`/`io_uring_enter` submitting an `IORING_OP_WAITID` SQE) plus process-management signals, all of which require local access to the system. Per kernel scoring guidance, io_uring bugs are Local.\nAC:L - The attacker controls both sides of the race: it drives the wait-queue wakeups at arbitrary rate by forking children and looping SIGSTOP/SIGCONT (`do_notify_parent_cldstop` \u2192 `__wake_up_parent`), while concurrently submitting `IORING_OP_ASYNC_CANCEL` or tearing down the ring from another thread to grab the competing reference. syzbot produced a working reproducer and confirmed the fix, showing the window is hit reliably.\nPR:L - Any unprivileged local user can create an io_uring ring \u2014 `sysctl_io_uring_disabled` defaults to 0 and `IORING_OP_WAITID` carries no capability check \u2014 and waiting on one\u0027s own forked children needs no privilege at all. No capabilities, user namespaces, or root are required.\nUI:N - The attacker\u0027s own process performs every step: submitting the waitid SQE, forking and signalling the children that generate wakeups, and issuing the concurrent cancel. No action by any other user is needed.\nS:U - The use-after-free corrupts kernel heap memory and control flow within the same kernel security authority, yielding standard local privilege escalation. No VM, IOMMU, or other security-boundary crossing is involved.\nC:H - This is a use-after-free on a `struct io_waitid_async` allocated from a general-purpose kmalloc slab, which the attacker can reclaim and shape via heap spraying. The stale wait-queue entry is then dereferenced by `__wake_up_common()` and `list_del_init()`, giving a read primitive over reclaimed kernel memory that can be leveraged for arbitrary kernel memory disclosure.\nI:H - `list_del_init()` on the freed entry performs `prev-\u003enext = next; next-\u003eprev = prev` using pointers read from attacker-reclaimed memory, yielding a controlled write of a controlled pointer to a controlled address. Additionally `__wake_up_common()` calls `curr-\u003efunc(...)` on the freed entry, providing a direct indirect-call/control-flow hijack primitive leading to kernel code execution.\nA:H - Even without weaponization, the dangling wait-queue entry and the list-corrupting `list_del_init()` on freed memory produce KASAN splats, list debug BUGs, and kernel oopses/panics \u2014 this is exactly how syzbot detected it. The race can be re-triggered in a tight loop, so an unprivileged user can crash the machine at will."
