Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: clear acl_access/acl_default after releasing them
If getting acl_default fails, acl_access and acl_default will be released
simultaneously. However, acl_access will still retain a pointer pointing
to the released posix_acl, which will trigger a WARNING in
nfs3svc_release_getacl like this:
------------[ cut here ]------------

Summary
In the Linux kernel, the following vulnerability has been resolved:
ubifs: authentication: Fix use-after-free in ubifs_tnc_end_commit
After an insertion in TNC, the tree might split and cause a node to
change its `znode->parent`. A further deletion of other nodes in the
tree (which also could free the nodes), the aforementioned node's
`znode->cparent` could still point to a freed node. This
`znode->cparent` may not be updated when getting nodes to commit in
`ubifs_tnc_start_commit()`. This could then trigger a use-after-free
when accessing the `znode->cparent` in `write_index()` in
`ubifs_tnc_end_commit()`.
This can be triggered by running
rm -f /etc/test-file.bin
dd if=/dev/urandom of=/etc/test-file.bin bs=1M count=60 conv=fsync
in a loop, and with `CONFIG_UBIFS_FS_AUTHENTICATION`. KASAN then
reports:

The offending `memcpy()` in `ubifs_copy_hash()` has a use-after-free
when a node becomes root in TNC but still has a `cparent` to an already
freed node. More specifically, consider the following TNC:
zroot
/
/
zp1
/
/
zn
Inserting a new node `zn_new` with a key smaller then `zn` will trigger
a split in `tnc_insert()` if `zp1` is full:
zroot
/ \
/ \
zp1 zp2
/ \
/ \
zn_new zn
`zn->parent` has now been moved to `zp2`, *but* `zn->cparent` still
points to `zp1`.
Now, consider a removal of all the nodes _except_ `zn`. Just when
`tnc_delete()` is about to delete `zroot` and `zp2`:
zroot
\
\
zp2
\
\
zn
`zroot` and `zp2` get freed and the tree collapses:
zn
`zn` now becomes the new `zroot`.
`get_znodes_to_commit()` will now only find `zn`, the new `zroot`, and
`write_index()` will check its `znode->cparent` that wrongly points to
the already freed `zp1`. `ubifs_copy_hash()` thus gets wrongly called
with `znode->cparent->zbranch[znode->iip].hash` that triggers the
use-after-free!
Fix this by explicitly setting `znode->cparent` to `NULL` in
`get_znodes_to_commit()` for the root node. The search for the dirty
nodes

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: atlantic: eliminate double free in error handling logic
Driver has a logic leak in ring data allocation/free,
where aq_ring_free could be called multiple times on same ring,
if system is under stress and got memory allocation error.
Ring pointer was used as an indicator of failure, but this is
not correct since only ring data is allocated/deallocated.
Ring itself is an array member.
Changing ring allocation functions to return error code directly.
This simplifies error handling and eliminates aq_ring_free
on higher layer.

No capability, and no CIFS mount ownership, is required.\nUI:N - No victim action is needed: the attacker\u0027s own access to a multiuser mount creates and tears down per-fsuid SMB sessions, and ordinary background CIFS mount/reconnect/prune activity supplies the teardown otherwise.\nS:U - The use-after-free occurs in kernel memory and its effects stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Contents of the freed `cifs_tcon` \u2014 including `tree_name` printed with `%s`, which reads until a NUL and can run past the freed object \u2014 are copied into the seq_file buffer returned to the unprivileged reader, yielding a kernel heap disclosure that can be aimed at reallocated sensitive data via heap grooming.\nI:H - A use-after-free of this class gives the attacker influence over the freed slab object\u0027s contents, letting dereferenced pointers (`server-\u003eops-\u003eprint_stats`, tcon list links) be steered by heap spraying into a control-flow/corruption primitive rather than a mere stale read.\nA:H - The confirmed sibling bug produced a general protection fault on slab poison in exactly this traversal, and the oops happens while the global `cifs_tcp_ses_lock` spinlock is held, hanging all subsequent CIFS operations system-wide on top of killing the faulting task."

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: properly validate chunk size in sctp_sf_ootb()
A size validation fix similar to that in Commit 50619dbf8db7 ("sctp: add
size validation when walking chunks") is also required in sctp_sf_ootb()
to address a crash reported by syzbot:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix out of bounds reads when finding clock sources
The current USB-audio driver code doesn't check bLength of each
descriptor at traversing for clock descriptors. That is, when a
device provides a bogus descriptor with a shorter bLength, the driver
might hit out-of-bounds reads.
For addressing it, this patch adds sanity checks to the validator
functions for the clock descriptor traversal. When the descriptor
length is shorter than expected, it's skipped in the loop.
For the clock source and clock multiplier descriptors, we can just
check bLength against the sizeof() of each descriptor type.
OTOH, the clock selector descriptor of UAC2 and UAC3 has an array
of bNrInPins elements and two more fields at its tail, hence those
have to be checked in addition to the sizeof() check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: Always pass notifications when child class becomes empty
Certain classful qdiscs may invoke their classes' dequeue handler on an
enqueue operation. This may unexpectedly empty the child qdisc and thus
make an in-flight class passive via qlen_notify(). Most qdiscs do not
expect such behaviour at this point in time and may re-activate the
class eventually anyways which will lead to a use-after-free.
The referenced fix commit attempted to fix this behavior for the HFSC
case by moving the backlog accounting around, though this turned out to
be incomplete since the parent's parent may run into the issue too.
The following reproducer demonstrates this use-after-free:
tc qdisc add dev lo root handle 1: drr
tc filter add dev lo parent 1: basic classid 1:1
tc class add dev lo parent 1: classid 1:1 drr
tc qdisc add dev lo parent 1:1 handle 2: hfsc def 1
tc class add dev lo parent 2: classid 2:1 hfsc rt m1 8 d 1 m2 0
tc qdisc add dev lo parent 2:1 handle 3: netem
tc qdisc add dev lo parent 3:1 handle 4: blackhole
echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888
tc class delete dev lo classid 1:1
echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888
Since backlog accounting issues leading to a use-after-frees on stale
class pointers is a recurring pattern at this point, this patch takes
a different approach. Instead of trying to fix the accounting, the patch
ensures that qdisc_tree_reduce_backlog always calls qlen_notify when
the child qdisc is empty. This solves the problem because deletion of
qdiscs always involves a call to qdisc_reset() and / or
qdisc_purge_queue() which ultimately resets its qlen to 0 thus causing
the following qdisc_tree_reduce_backlog() to report to the parent. Note
that this may call qlen_notify on passive classes multiple times. This
is not a problem after the recent patch series that made all the
classful qdiscs qlen_notify() handlers idempotent.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: Always pass notifications when child class becomes empty\n\nCertain classful qdiscs may invoke their classes\u0027 dequeue handler on an\nenqueue operation. This may unexpectedly empty the child qdisc and thus\nmake an in-flight class passive via qlen_notify(). Most qdiscs do not\nexpect such behaviour at this point in time and may re-activate the\nclass eventually anyways which will lead to a use-after-free.\n\nThe referenced fix commit attempted to fix this behavior for the HFSC\ncase by moving the backlog accounting around, though this turned out to\nbe incomplete since the parent\u0027s parent may run into the issue too.\nThe following reproducer demonstrates this use-after-free:\n\n tc qdisc add dev lo root handle 1: drr\n tc filter add dev lo parent 1: basic classid 1:1\n tc class add dev lo parent 1: classid 1:1 drr\n tc qdisc add dev lo parent 1:1 handle 2: hfsc def 1\n tc class add dev lo parent 2: classid 2:1 hfsc rt m1 8 d 1 m2 0\n tc qdisc add dev lo parent 2:1 handle 3: netem\n tc qdisc add dev lo parent 3:1 handle 4: blackhole\n\n echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888\n tc class delete dev lo classid 1:1\n echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888\n\nSince backlog accounting issues leading to a use-after-frees on stale\nclass pointers is a recurring pattern at this point, this patch takes\na different approach. Instead of trying to fix the accounting, the patch\nensures that qdisc_tree_reduce_backlog always calls qlen_notify when\nthe child qdisc is empty. This solves the problem because deletion of\nqdiscs always involves a call to qdisc_reset() and / or\nqdisc_purge_queue() which ultimately resets its qlen to 0 thus causing\nthe following qdisc_tree_reduce_backlog() to report to the parent. Note\nthat this may call qlen_notify on passive classes multiple times. This\nis not a problem after the recent patch series that made all the\nclassful qdiscs qlen_notify() handlers idempotent."

Any host that can reach the exported NFS service can trigger it.\nUI:N - The whole sequence is issued by the attacking NFS client; no administrator or local user on the server has to mount anything, open a file, or take any action.\nS:U - The fault occurs in the nfsd callback workqueue inside the kernel\u0027s own security authority, and the damage is confined to that kernel instance.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i3c: master: cdns: Fix use after free vulnerability in cdns_i3c_master Driver Due to Race Condition
In the cdns_i3c_master_probe function, &master->hj_work is bound with
cdns_i3c_master_hj. And cdns_i3c_master_interrupt can call
cnds_i3c_master_demux_ibis function to start the work.
If we remove the module which will call cdns_i3c_master_remove to
make cleanup, it will free master->base through i3c_master_unregister
while the work mentioned above will be used. The sequence of operations
that may lead to a UAF bug is as follows:
CPU0 CPU1
| cdns_i3c_master_hj
cdns_i3c_master_remove |
i3c_master_unregister(&master->base) |
device_unregister(&master->dev) |
device_release |
//free master->base |
| i3c_master_do_daa(&master->base)
| //use master->base
Fix it by ensuring that the work is canceled before proceeding with
the cleanup in cdns_i3c_master_remove.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: pxafb: Fix possible use after free in pxafb_task()
In the pxafb_probe function, it calls the pxafb_init_fbinfo function,
after which &fbi->task is associated with pxafb_task. Moreover,
within this pxafb_init_fbinfo function, the pxafb_blank function
within the &pxafb_ops struct is capable of scheduling work.
If we remove the module which will call pxafb_remove to make cleanup,
it will call unregister_framebuffer function which can call
do_unregister_framebuffer to free fbi->fb through
put_fb_info(fb_info), while the work mentioned above will be used.
The sequence of operations that may lead to a UAF bug is as follows:
CPU0 CPU1
| pxafb_task
pxafb_remove |
unregister_framebuffer(info) |
do_unregister_framebuffer(fb_info) |
put_fb_info(fb_info) |
// free fbi->fb | set_ctrlr_state(fbi, state)
| __pxafb_lcd_power(fbi, 0)
| fbi->lcd_power(on, &fbi->fb.var)
| //use fbi->fb
Fix it by ensuring that the work is canceled before proceeding
with the cleanup in pxafb_remove.
Note that only root user can remove the driver at runtime.

No network or physical device manipulation is involved.\nAC:L - The attacker deterministically arms the race by repeatedly queueing `pxafb_task` via `FBIOBLANK`, and the racing work sleeps up to 200 ms in `wait_for_completion_timeout(\u0026fbi-\u003edisable_done, ...)` inside `pxafb_disable_controller()`, giving an enormous, reliably winnable window. No error path, unusual memory layout, or non-default configuration is required \u2014 `CONFIG_FB_PXA` is standard and tristate on every PXA platform.\nPR:L - An ordinary unprivileged user needs only DAC access to `/dev/fb0` \u2014 which requires no capability and is routinely granted on the embedded PXA handhelds and panel devices this driver targets \u2014 to queue the work and groom the slab that backs the freed `pxafb_info`. This matches this CNA\u0027s established treatment of driver-teardown UAFs (e.g. CVE-2025-21976, hyperv_fb), where `PR:H` is reserved for cases that cross a VM/container security boundary.\nUI:N - No victim action such as opening a file or mounting a filesystem is needed; the pending work is also queued automatically by the fbcon console-blank timer and by `pxafb_set_par()`, so the race can be live without any interactive user.\nS:U - The corrupted memory and the resulting code execution are both in the host kernel\u0027s own security authority, with no VM, IOMMU, or sandbox boundary crossed.\nC:H - The use-after-free lets the attacker control the contents of the reallocated `pxafb_info`, including `fbi-\u003emmio_base`, which `lcd_readl()` dereferences \u2014 yielding an attacker-directed read primitive that, combined with the hijacked control flow, permits disclosure of arbitrary kernel memory.\nI:H - `__pxafb_lcd_power()` and `__pxafb_backlight_power()` call `fbi-\u003elcd_power()` / `fbi-\u003ebacklight_power()` \u2014 function pointers read straight out of the freed allocation \u2014 and `lcd_writel()` performs `__raw_writel()` to an address taken from the same freed object, giving both control-flow hijack and an arbitrary write.\nA:H - Even without successful exploitation the UAF reliably oopses the kernel \u2014 dereferencing a freed `mmio_base`, locking a freed mutex, or on `rmmod` executing `pxafb_task` text that has already been unmapped with the module."

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: at_xdmac: avoid null_prt_deref in at_xdmac_prep_dma_memset
The at_xdmac_memset_create_desc may return NULL, which will lead to a
null pointer dereference. For example, the len input is error, or the
atchan->free_descs_list is empty and memory is exhausted. Therefore, add
check to avoid this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: propagate directory read errors from nilfs_find_entry()
Syzbot reported that a task hang occurs in vcs_open() during a fuzzing
test for nilfs2.
The root cause of this problem is that in nilfs_find_entry(), which
searches for directory entries, ignores errors when loading a directory
page/folio via nilfs_get_folio() fails.
If the filesystem images is corrupted, and the i_size of the directory
inode is large, and the directory page/folio is successfully read but
fails the sanity check, for example when it is zero-filled,
nilfs_check_folio() may continue to spit out error messages in bursts.
Fix this issue by propagating the error to the callers when loading a
page/folio fails in nilfs_find_entry().
The current interface of nilfs_find_entry() and its callers is outdated
and cannot propagate error codes such as -EIO and -ENOMEM returned via
nilfs_find_entry(), so fix it together.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HSI: ssi_protocol: Fix use after free vulnerability in ssi_protocol Driver Due to Race Condition
In the ssi_protocol_probe() function, &ssi->work is bound with
ssip_xmit_work(), In ssip_pn_setup(), the ssip_pn_xmit() function
within the ssip_pn_ops structure is capable of starting the
work.
If we remove the module which will call ssi_protocol_remove()
to make a cleanup, it will free ssi through kfree(ssi),
while the work mentioned above will be used. The sequence
of operations that may lead to a UAF bug is as follows:
CPU0 CPU1
| ssip_xmit_work
ssi_protocol_remove |
kfree(ssi); |
| struct hsi_client *cl = ssi->cl;
| // use ssi
Fix it by ensuring that the work is canceled before proceeding
with the cleanup in ssi_protocol_remove().

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: go7007: fix a memleak in go7007_load_encoder
In go7007_load_encoder, bounce(i.e. go->boot_fw), is allocated without
a deallocation thereafter. After the following call chain:
saa7134_go7007_init
|-> go7007_boot_encoder
|-> go7007_load_encoder
|-> kfree(go)
go is freed and thus bounce is leaked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/packet: fix a race in packet_set_ring() and packet_notifier()
When packet_set_ring() releases po->bind_lock, another thread can
run packet_notifier() and process an NETDEV_UP event.
This race and the fix are both similar to that of commit 15fe076edea7
("net/packet: fix a race in packet_bind() and packet_notifier()").
There too the packet_notifier NETDEV_UP event managed to run while a
po->bind_lock critical section had to be temporarily released. And
the fix was similarly to temporarily set po->num to zero to keep
the socket unhooked until the lock is retaken.
The po->bind_lock in packet_set_ring and packet_notifier precede the
introduction of git history.

---[ end trace 0000000000000000 ]---
Its possible that two threads call tcp_v6_do_rcv()/sk_forward_alloc_add()
concurrently when sk->sk_state == TCP_LISTEN with sk->sk_lock unlocked,
which triggers a data-race around sk->sk_forward_alloc:
tcp_v6_rcv
tcp_v6_do_rcv
skb_clone_and_charge_r
sk_rmem_schedule
__sk_mem_schedule
sk_forward_alloc_add()
skb_set_owner_r
sk_mem_charge
sk_forward_alloc_add()
__kfree_skb
skb_release_all
skb_release_head_state
sock_rfree
sk_mem_uncharge
sk_forward_alloc_add()
sk_mem_reclaim
// set local var reclaimable
__sk_mem_reclaim
sk_forward_alloc_add()
In this syzkaller testcase, two threads call
tcp_v6_do_rcv() with skb->truesize=768, the sk_forward_alloc changes like
this:
(cpu 1) | (cpu 2) | sk_forward_alloc
... | ... | 0
__sk_mem_schedule() | | +4096 = 4096
| __sk_mem_schedule() | +4096 = 8192
sk_mem_charge() | | -768 = 7424
| sk_mem_charge() | -768 = 6656
... | ... |
sk_mem_uncharge() | | +768 = 7424
reclaimable=7424 | |
| sk_mem_uncharge() | +768 = 8192
| reclaimable=8192 |
__sk_mem_reclaim() | | -4096 = 4096
| __sk_mem_reclaim() | -8192 = -4096 != 0
The skb_clone_and_charge_r() should not be called in tcp_v6_do_rcv() when
sk->sk_state is TCP_LISTEN, it happens later in tcp_v6_syn_recv_sock().
Fix the same issue in dccp_v6_do_rcv().

The same defect exists in the DCCP IPv6 receive path.\nAC:L - The attacker controls both sides of the race by sending a burst of concurrent SYNs from different source ports/addresses, which RSS/RPS distributes across CPUs that all enter `tcp_v6_do_rcv()` on the same listener with no socket lock held. No memory layout, timing window outside attacker influence, or victim state is required, and syzkaller reproduces it routinely.\nPR:N - The racing code runs while processing a SYN on a listening socket, entirely before connection establishment or any authentication, so no credentials of any kind are needed. Setting the `IPV6_RECV*` option that arms the path is done by the victim server (or by an unprivileged local user on their own listener), not by the attacker.\nUI:N - Triggering requires only that packets be sent to an already-listening socket; no action by any local user or administrator is needed.\nS:U - The corrupted state (`sk-\u003esk_forward_alloc`, `tcp_memory_allocated`, memcg skmem counters) and the resulting warning/panic are all within the kernel\u0027s own security authority, with no crossing into a hypervisor, IOMMU, or other separate authority.\nC:N - The defect is a non-atomic read-modify-write on integer accounting counters; it produces no out-of-bounds read, no use-after-free, and no path by which memory contents or kernel pointers are disclosed to the attacker.\nI:N - No attacker-controlled data is written and no memory corruption primitive is created \u2014 only the socket\u0027s own memory-accounting counters become inconsistent, which is not a modification of protected data or control flow.\nA:H - The imbalance trips `WARN_ON_ONCE(sk_forward_alloc_get(sk))` in `inet_sock_destruct()` from softirq context, which is an immediate kernel panic on `panic_on_warn` systems, and the over-reclaim corrupts the global `tcp_memory_allocated` counter and memcg skmem accounting, breaking system-wide TCP memory limits (unbounded growth toward OOM, or permanent memory pressure across all TCP sockets). It is repeatable at will by an unauthenticated remote attacker."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netrom: Fix a memory leak in nr_heartbeat_expiry()
syzbot reported a memory leak in nr_create() [0].
Commit 409db27e3a2e ("netrom: Fix use-after-free of a listening socket.")
added sock_hold() to the nr_heartbeat_expiry() function, where
a) a socket has a SOCK_DESTROY flag or
b) a listening socket has a SOCK_DEAD flag.
But in the case "a," when the SOCK_DESTROY flag is set, the file descriptor
has already been closed and the nr_release() function has been called.
So it makes no sense to hold the reference count because no one will
call another nr_destroy_socket() and put it as in the case "b."
nr_connect
nr_establish_data_link
nr_start_heartbeat
nr_release
switch (nr->state)
case NR_STATE_3
nr->state = NR_STATE_2
sock_set_flag(sk, SOCK_DESTROY);
nr_rx_frame
nr_process_rx_frame
switch (nr->state)
case NR_STATE_2
nr_state2_machine()
nr_disconnect()
nr_sk(sk)->state = NR_STATE_0
sock_set_flag(sk, SOCK_DEAD)
nr_heartbeat_expiry
switch (nr->state)
case NR_STATE_0
if (sock_flag(sk, SOCK_DESTROY) ||
(sk->sk_state == TCP_LISTEN
&& sock_flag(sk, SOCK_DEAD)))
sock_hold() // ( !!! )
nr_destroy_socket()
To fix the memory leak, let's call sock_hold() only for a listening socket.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Do not allow binding to VMADDR_PORT_ANY
It is possible for a vsock to autobind to VMADDR_PORT_ANY. This can
cause a use-after-free when a connection is made to the bound socket.
The socket returned by accept() also has port VMADDR_PORT_ANY but is not
on the list of unbound sockets. Binding it will result in an extra
refcount decrement similar to the one fixed in fcdd2242c023 (vsock: Keep
the binding until socket destruction).
Modify the check in __vsock_bind_connectible() to also prevent binding
to VMADDR_PORT_ANY.

Summary
In the Linux kernel, the following vulnerability has been resolved:
team: fix null-ptr-deref when team device type is changed
Get a null-ptr-deref bug as follows with reproducer [1].

When enslave a vlan device to team device and team device type is changed
from non-ether to ether, header_ops of team device is changed to
vlan_header_ops. That is incorrect and will trigger null-ptr-deref
for vlan->real_dev in vlan_dev_hard_header() because team device is not
a vlan device.
Cache eth_header_ops in team_setup(), then assign cached header_ops to
header_ops of team net device when its type is changed from non-ether
to ether to fix the bug.

"value": "AV:L - The bug is triggered by local rtnetlink configuration (creating a team device and enslaving nlmon then vlan ports via IFLA_MASTER), not by processing unauthenticated remote packets; subsequent hard_header calls occur on that locally configured device.\nAC:L - The reproducer topology is fully attacker-controlled and deterministically installs vlan_header_ops on the team device when changing type from non-ether to ether; no race or external timing condition is required.\nPR:L - Creating team/dummy/vlan/nlmon devices and enslaving them requires CAP_NET_ADMIN enforced via netlink_net_capable() in the network namespace\u0027s user_ns, which an unprivileged user obtains with unshare -Urn; GENL_ADMIN_PERM (init userns) is not required for this path.\nUI:N - The attacker configures the devices and triggers packet transmission (e.g., IPv6 MLD on bring-up or local socket send) without any action by another user.\nS:U - Impact remains within the same kernel security authority (local DoS / type-confusion privilege impact); there is no VM escape, IOMMU bypass, or other cross-boundary effect.\nC:H - Installing vlan_header_ops on a non-vlan team device is header_ops type confusion: vlan_dev_hard_header interprets team private data as vlan_dev_priv (including pointer walks such as egress_priority_map), which can expose kernel memory; scored high per type-confusion guidance and CVE-2026-31502.\nI:H - Type confusion in kernel header_ops callback dispatch misinterprets object layout and can yield write/control-flow primitives beyond the observed crash; kernel type confusion is scored as high integrity impact.\nA:H - The demonstrated failure mode is a kernel NULL pointer dereference oops in vlan_dev_hard_header when the confused real_dev/layout is used, which is a high availability impact."

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: hub: Guard against accesses to uninitialized BOS descriptors
Many functions in drivers/usb/core/hub.c and drivers/usb/core/hub.h
access fields inside udev->bos without checking if it was allocated and
initialized. If usb_get_bos_descriptor() fails for whatever
reason, udev->bos will be NULL and those accesses will result in a
crash:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix OOB read when checking dotdot dir
Mounting a corrupted filesystem with directory which contains '.' dir
entry with rec_len == block size results in out-of-bounds read (later
on, when the corrupted directory is removed).
ext4_empty_dir() assumes every ext4 directory contains at least '.'
and '..' as directory entries in the first data block. It first loads
the '.' dir entry, performs sanity checks by calling ext4_check_dir_entry()
and then uses its rec_len member to compute the location of '..' dir
entry (in ext4_next_entry). It assumes the '..' dir entry fits into the
same data block.
If the rec_len of '.' is precisely one block (4KB), it slips through the
sanity checks (it is considered the last directory entry in the data
block) and leaves "struct ext4_dir_entry_2 *de" point exactly past the
memory slot allocated to the data block. The following call to
ext4_check_dir_entry() on new value of de then dereferences this pointer
which results in out-of-bounds mem access.
Fix this by extending __ext4_check_dir_entry() to check for '.' dir
entries that reach the end of data block. Make sure to ignore the phony
dir entries for checksum (by checking name_len for non-zero).
Note: This is reported by KASAN as use-after-free in case another
structure was recently freed from the slot past the bound, but it is
really an OOB read.
This issue was found by syzkaller tool.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix OOB read when checking dotdot dir\n\nMounting a corrupted filesystem with directory which contains \u0027.\u0027 dir\nentry with rec_len == block size results in out-of-bounds read (later\non, when the corrupted directory is removed).\n\next4_empty_dir() assumes every ext4 directory contains at least \u0027.\u0027\nand \u0027..\u0027 as directory entries in the first data block. It first loads\nthe \u0027.\u0027 dir entry, performs sanity checks by calling ext4_check_dir_entry()\nand then uses its rec_len member to compute the location of \u0027..\u0027 dir\nentry (in ext4_next_entry). It assumes the \u0027..\u0027 dir entry fits into the\nsame data block.\n\nIf the rec_len of \u0027.\u0027 is precisely one block (4KB), it slips through the\nsanity checks (it is considered the last directory entry in the data\nblock) and leaves \"struct ext4_dir_entry_2 *de\" point exactly past the\nmemory slot allocated to the data block. The following call to\next4_check_dir_entry() on new value of de then dereferences this pointer\nwhich results in out-of-bounds mem access.\n\nFix this by extending __ext4_check_dir_entry() to check for \u0027.\u0027 dir\nentries that reach the end of data block. Make sure to ignore the phony\ndir entries for checksum (by checking name_len for non-zero).\n\nNote: This is reported by KASAN as use-after-free in case another\nstructure was recently freed from the slot past the bound, but it is\nreally an OOB read.\n\nThis issue was found by syzkaller tool.\n\nCall Trace:\n[ 38.594108] BUG: KASAN: slab-use-after-free in __ext4_check_dir_entry+0x67e/0x710\n[ 38.594649] Read of size 2 at addr ffff88802b41a004 by task syz-executor/5375\n[ 38.595158]\n[ 38.595288] CPU: 0 UID: 0 PID: 5375 Comm: syz-executor Not tainted 6.14.0-rc7 #1\n[ 38.595298] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014\n[ 38.595304] Call Trace:\n[ 38.595308] \u003cTASK\u003e\n[ 38.595311] dump_stack_lvl+0xa7/0xd0\n[ 38.595325] print_address_description.constprop.0+0x2c/0x3f0\n[ 38.595339] ? __ext4_check_dir_entry+0x67e/0x710\n[ 38.595349] print_report+0xaa/0x250\n[ 38.595359] ? __ext4_check_dir_entry+0x67e/0x710\n[ 38.595368] ? kasan_addr_to_slab+0x9/0x90\n[ 38.595378] kasan_report+0xab/0xe0\n[ 38.595389] ? __ext4_check_dir_entry+0x67e/0x710\n[ 38.595400] __ext4_check_dir_entry+0x67e/0x710\n[ 38.595410] ext4_empty_dir+0x465/0x990\n[ 38.595421] ? __pfx_ext4_empty_dir+0x10/0x10\n[ 38.595432] ext4_rmdir.part.0+0x29a/0xd10\n[ 38.595441] ? __dquot_initialize+0x2a7/0xbf0\n[ 38.595455] ? __pfx_ext4_rmdir.part.0+0x10/0x10\n[ 38.595464] ? __pfx___dquot_initialize+0x10/0x10\n[ 38.595478] ? down_write+0xdb/0x140\n[ 38.595487] ? __pfx_down_write+0x10/0x10\n[ 38.595497] ext4_rmdir+0xee/0x140\n[ 38.595506] vfs_rmdir+0x209/0x670\n[ 38.595517] ? lookup_one_qstr_excl+0x3b/0x190\n[ 38.595529] do_rmdir+0x363/0x3c0\n[ 38.595537] ? __pfx_do_rmdir+0x10/0x10\n[ 38.595544] ? strncpy_from_user+0x1ff/0x2e0\n[ 38.595561] __x64_sys_unlinkat+0xf0/0x130\n[ 38.595570] do_syscall_64+0x5b/0x180\n[ 38.595583] entry_SYSCALL_64_after_hwframe+0x76/0x7e"

Local attack vector scores higher than physical and correctly models USB/auto-mount and loop-mount delivery.\nAC:L - The condition is fully deterministic and entirely attacker-authored \u2014 setting the `.` entry\u0027s `rec_len` to exactly the block size in the image reliably slips past every sanity check in `__ext4_check_dir_entry()` and lands `de` past the block on every attempt. No race, timing, or uncontrolled memory-layout requirement.\nPR:L - Once the image is mounted (via udisks2/GNOME auto-mount of removable media on desktops and kiosks, or an fstab `user` entry), any unprivileged local user with ordinary access to the mount can invoke `rmdir` and reach `ext4_empty_dir()`; no capability check gates the path.\nUI:N - In the auto-mount scenario the attacker performs both steps themselves \u2014 inserting the media triggers the mount automatically and the same attacker issues the `rmdir` \u2014 so no action by a separate user is required.\nS:U - The out-of-bounds access, the disclosure, and the panic all occur within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The read reaches into the adjacent slab object/page and its contents are exfiltrated to userspace-visible dmesg through `ext4_error_inode()`, which prints the out-of-bounds `inode` and `rec_len` fields verbatim. The operation is cheaply repeatable and the neighbouring slot can be heap-groomed, making it a practical kernel heap/pointer disclosure primitive rather than a bounded one-shot leak.\nI:H - Data read out of bounds directly controls subsequent logic \u2014 if the adjacent heap bytes decode as a valid `..` entry, `ext4_empty_dir()` wrongly reports the directory empty and `rmdir`/`rename` proceeds to unlink a non-empty directory, and the OOB `rec_len` drives the following offset walk. KASAN classifies the access as a use-after-free on the neighbouring freed object, so attacker-groomed heap state translates into corrupted filesystem-metadata operations.\nA:H - The error path is reached with the attacker-controlled superblock, and `s_errors = EXT4_ERRORS_PANIC` (`fs/ext4/super.c:4364`) makes `ext4_error_inode()` call `panic()` at `super.c:735`, giving a guaranteed kernel panic. Independently, the read past the block can fault on an unmapped or poisoned page, and on debug/KASAN kernels it is an immediate BUG."

Summary
In the Linux kernel, the following vulnerability has been resolved:
padata: fix UAF in padata_reorder
A bug was found when run ltp test:
BUG: KASAN: slab-use-after-free in padata_find_next+0x29/0x1a0
Read of size 4 at addr ffff88bbfe003524 by task kworker/u113:2/3039206

padata_parallel_worker+0x3d/0xc0
process_one_work+0x2ec/0x5a0
If 'mdelay(10)' is added before calling 'padata_find_next' in the
'padata_reorder' function, this issue could be reproduced easily with
ltp test (pcrypt_aead01).
This can be explained as bellow:
pcrypt_aead_encrypt
...
padata_do_parallel
refcount_inc(&pd->refcnt); // add refcnt
...
padata_do_serial
padata_reorder // pd
while (1) {
padata_find_next(pd, true); // using pd
queue_work_on
...
padata_serial_worker crypto_del_alg
padata_put_pd_cnt // sub refcnt
padata_free_shell
padata_put_pd(ps->pd);
// pd is freed
// loop again, but pd is freed
// call padata_find_next, UAF
}
In the padata_reorder function, when it loops in 'while', if the alg is
deleted, the refcnt may be decreased to 0 before entering
'padata_find_next', which leads to UAF.
As mentioned in [1], do_serial is supposed to be called with BHs disabled
and always happen under RCU protection, to address this issue, add
synchronize_rcu() in 'padata_free_shell' wait for all _do_serial calls
to finish.

The commit confirms it reproduces with a stock LTP test (pcrypt_aead01) once the loop is delayed, meaning it is a naturally occurring, repeatable window.\nPR:L - A basic unprivileged local user can both instantiate and continuously drive pcrypt via AF_ALG (`alg_bind` performs no capability check) and trigger the teardown side, since `crypto_alg_finish_registration()` \u2192 `crypto_remove_spawns()` destroys the pcrypt instance when an equal-or-higher-priority same-named implementation registers \u2014 a module autoload reachable from the same unprivileged bind path.\nUI:N - Exploitation is entirely attacker-driven through socket operations and crypto requests; no victim action, mount, or file open is required.\nS:U - The use-after-free corrupts kernel slab memory and stays within the kernel\u0027s own security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - Reclaiming the freed `struct parallel_data` gives the attacker control of `pd-\u003ereorder_list`, whose per-CPU dereference in `padata_find_next()` becomes an attacker-directed kernel read, and `pd-\u003eps-\u003epinst` is likewise dereferenced \u2014 yielding disclosure of arbitrary kernel memory.\nI:H - The same UAF provides write primitives \u2014 `list_del_init()` unlink on an attacker-controlled reorder list, `++pd-\u003eprocessed` / `pd-\u003ecpu` writes, and most severely `queue_work(pinst-\u003eserial_wq, \u0026pd-\u003ereorder_work)` invoking a function pointer living in freed, sprayable memory, enabling control-flow hijack and privilege escalation.\nA:H - Even unweaponized, the slab-use-after-free reported by KASAN dereferences freed percpu and workqueue pointers from a kworker context, reliably producing an oops or kernel panic and taking the system down."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix race between element replace and close()
Element replace (with a socket different from the one stored) may race
with socket's close() link popping & unlinking. __sock_map_delete()
unconditionally unrefs the (wrong) element:
// set map[0] = s0
map_update_elem(map, 0, s0)
// drop fd of s0
close(s0)
sock_map_close()
lock_sock(sk) (s0!)
sock_map_remove_links(sk)
link = sk_psock_link_pop()
sock_map_unlink(sk, link)
sock_map_delete_from_link
// replace map[0] with s1
map_update_elem(map, 0, s1)
sock_map_update_elem
(s1!) lock_sock(sk)
sock_map_update_common
psock = sk_psock(sk)
spin_lock(&stab->lock)
osk = stab->sks[idx]
sock_map_add_link(..., &stab->sks[idx])
sock_map_unref(osk, &stab->sks[idx])
psock = sk_psock(osk)
sk_psock_put(sk, psock)
if (refcount_dec_and_test(&psock))
sk_psock_drop(sk, psock)
spin_unlock(&stab->lock)
unlock_sock(sk)
__sock_map_delete
spin_lock(&stab->lock)
sk = *psk // s1 replaced s0; sk == s1
if (!sk_test || sk_test == sk) // sk_test (s0) != sk (s1); no branch
sk = xchg(psk, NULL)
if (sk)
sock_map_unref(sk, psk) // unref s1; sks[idx] will dangle
psock = sk_psock(sk)
sk_psock_put(sk, psock)
if (refcount_dec_and_test())
sk_psock_drop(sk, psock)
spin_unlock(&stab->lock)
release_sock(sk)
Then close(map) enqueues bpf_map_free_deferred, which finally calls
sock_map_free(). This results in some refcount_t warnings along with
a KASAN splat [1].
Fix __sock_map_delete(), do not allow sock_map_unref() on elements that
may have been replaced.

"value": "AV:L - Both halves of the race are local syscalls \u2014 `bpf(BPF_MAP_UPDATE_ELEM)` on a sockmap fd and `close()` on a sockmap\u0027d socket \u2014 with no remote peer data involved in reaching `__sock_map_delete()`. Sockmap element replace and socket teardown are driven entirely from the local host.\nAC:L - The attacker controls both sides of the race, running one thread looping `close()` on sockmap\u0027d sockets and another looping `map_update_elem()` to replace the same index, so the window is created and retried by the attacker rather than depending on any external condition. Nothing about the race depends on victim state or memory layout the attacker cannot influence, and the reporter reproduced it with a KASAN splat.\nPR:L - Creating the sockmap requires `CAP_NET_ADMIN`, but `bpf_token_capable()` grants it at `ns_capable()` level inside a user namespace via delegated BPF tokens, and `CAP_NET_ADMIN` is routinely handed to container and network-agent workloads. Once the map fd exists, `map_update_elem()` and `close()` need no further privilege, so an ordinary unprivileged-in-init-ns user reaches this path.\nUI:N - The attacker creates the sockmap, inserts its own sockets, and drives both racing threads entirely on its own. No victim action \u2014 no mount, no file open, no third-party interaction \u2014 is required.\nS:U - The refcount underflow, premature `sk_psock_drop()`, and resulting use-after-free are all confined to kernel memory and the socket/psock state managed by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The stray `sock_map_unref()` frees the `struct sock` while `stab-\u003esks[idx]` retains a dangling pointer, letting the attacker reclaim the freed slab object with controlled data and then read it back through `sock_map_lookup_sys()`/`__sock_gen_cookie()` or a `bpf_sk_redirect_map()` datapath dereference. A use-after-free on a `struct sock` exposes its `sk_prot`, callbacks, and adjacent heap contents, giving an arbitrary-read primitive.\nI:H - `sock_map_free()` performs a 4-byte use-after-free *write* into the freed socket (the KASAN splat) and `lock_sock()` on freed memory, while the torn link means the map keeps referencing a destroyed socket whose `sk_prot` function pointers are dereferenced on later redirect/lookup. Combined with the attacker-chosen reclaim window on the 1984-byte slab, this is a heap write and control-flow hijack primitive, not a bounded corruption.\nA:H - The bug produces `refcount_t` addition-on-zero and underflow warnings plus a KASAN slab-use-after-free in `sock_map_free()`, and the freed socket is later locked and dereferenced from a workqueue \u2014 with panic_on_warn or panic_on_oops this is an immediate kernel panic, and otherwise an oops in `bpf_map_free_deferred`. The attacker can retrigger it at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: sch_sfq: don't allow 1 packet limit
The current implementation does not work correctly with a limit of
1. iproute2 actually checks for this and this patch adds the check in
kernel as well.
This fixes the following syzkaller reported crash:
UBSAN: array-index-out-of-bounds in net/sched/sch_sfq.c:210:6
index 65535 is out of range for type 'struct sfq_head[128]'
CPU: 0 PID: 2569 Comm: syz-executor101 Not tainted 5.10.0-smp-DEV #1
Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 09/13/2024

The crash can be also be reproduced with the following (with a tc
recompiled to allow for sfq limits of 1):
tc qdisc add dev dummy0 handle 1: root tbf rate 1Kbit burst 100b lat 1s
../iproute2-6.9.0/tc/tc qdisc add dev dummy0 handle 2: parent 1:10 sfq limit 1
ifconfig dummy0 up
ping -I dummy0 -f -c2 -W0.1 8.8.8.8
sleep 1
Scenario that triggers the crash:
* the first packet is sent and queued in TBF and SFQ; qdisc qlen is 1
* TBF dequeues: it peeks from SFQ which moves the packet to the
gso_skb list and keeps qdisc qlen set to 1. TBF is out of tokens so
it schedules itself for later.
* the second packet is sent and TBF tries to queues it to SFQ. qdisc
qlen is now 2 and because the SFQ limit is 1 the packet is dropped
by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,
however q->tail is not NULL.
At this point, assuming no more packets are queued, when sch_dequeue
runs again it will decrement the qlen for the current empty slot
causing an underflow and the subsequent out of bounds access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
padata: Fix refcnt handling in padata_free_shell()
In a high-load arm64 environment, the pcrypt_aead01 test in LTP can lead
to system UAF (Use-After-Free) issues. Due to the lengthy analysis of
the pcrypt_aead01 function call, I'll describe the problem scenario
using a simplified model:
Suppose there's a user of padata named `user_function` that adheres to
the padata requirement of calling `padata_free_shell` after `serial()`
has been invoked, as demonstrated in the following code:
```c
struct request {
struct padata_priv padata;
struct completion *done;
};
void parallel(struct padata_priv *padata) {
do_something();
}
void serial(struct padata_priv *padata) {
struct request *request = container_of(padata,
struct request,
padata);
complete(request->done);
}
void user_function() {
DECLARE_COMPLETION(done)
padata->parallel = parallel;
padata->serial = serial;
padata_do_parallel();
wait_for_completion(&done);
padata_free_shell();
}
```
In the corresponding padata.c file, there's the following code:
```c
static void padata_serial_worker(struct work_struct *serial_work) {
...
cnt = 0;
while (!list_empty(&local_list)) {
...
padata->serial(padata);
cnt++;
}
local_bh_enable();
if (refcount_sub_and_test(cnt, &pd->refcnt))
padata_free_pd(pd);
}
```
Because of the high system load and the accumulation of unexecuted
softirq at this moment, `local_bh_enable()` in padata takes longer
to execute than usual. Subsequently, when accessing `pd->refcnt`,
`pd` has already been released by `padata_free_shell()`, resulting
in a UAF issue with `pd->refcnt`.
The fix is straightforward: add `refcount_dec_and_test` before calling
`padata_free_pd` in `padata_free_shell`.

Due to the lengthy analysis of\nthe pcrypt_aead01 function call, I\u0027ll describe the problem scenario\nusing a simplified model:\n\nSuppose there\u0027s a user of padata named `user_function` that adheres to\nthe padata requirement of calling `padata_free_shell` after `serial()`\nhas been invoked, as demonstrated in the following code:\n\n```c\nstruct request {\n struct padata_priv padata;\n struct completion *done;\n};\n\nvoid parallel(struct padata_priv *padata) {\n do_something();\n}\n\nvoid serial(struct padata_priv *padata) {\n struct request *request = container_of(padata,\n \t\t\t\tstruct request,\n\t\t\t\tpadata);\n complete(request-\u003edone);\n}\n\nvoid user_function() {\n DECLARE_COMPLETION(done)\n padata-\u003eparallel = parallel;\n padata-\u003eserial = serial;\n padata_do_parallel();\n wait_for_completion(\u0026done);\n padata_free_shell();\n}\n```\n\nIn the corresponding padata.c file, there\u0027s the following code:\n\n```c\nstatic void padata_serial_worker(struct work_struct *serial_work) {\n ...\n cnt = 0;\n\n while (!list_empty(\u0026local_list)) {\n ...\n padata-\u003eserial(padata);\n cnt++;\n }\n\n local_bh_enable();\n\n if (refcount_sub_and_test(cnt, \u0026pd-\u003erefcnt))\n padata_free_pd(pd);\n}\n```\n\nBecause of the high system load and the accumulation of unexecuted\nsoftirq at this moment, `local_bh_enable()` in padata takes longer\nto execute than usual. Subsequently, when accessing `pd-\u003erefcnt`,\n`pd` has already been released by `padata_free_shell()`, resulting\nin a UAF issue with `pd-\u003erefcnt`.\n\nThe fix is straightforward: add `refcount_dec_and_test` before calling\n`padata_free_pd` in `padata_free_shell`."

Summary
In the Linux kernel, the following vulnerability has been resolved:
posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()
If an exiting non-autoreaping task has already passed exit_notify() and
calls handle_posix_cpu_timers() from IRQ, it can be reaped by its parent
or debugger right after unlock_task_sighand().
If a concurrent posix_cpu_timer_del() runs at that moment, it won't be
able to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/or
lock_task_sighand() will fail.
Add the tsk->exit_state check into run_posix_cpu_timers() to fix this.
This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, because
exit_task_work() is called before exit_notify(). But the check still
makes sense, task_work_add(&tsk->posix_cputimers_work.work) will fail
anyway in this case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix null-ptr-deref in block_touch_buffer tracepoint
Patch series "nilfs2: fix null-ptr-deref bugs on block tracepoints".
This series fixes null pointer dereference bugs that occur when using
nilfs2 and two block-related tracepoints.
This patch (of 2):
It has been reported that when using "block:block_touch_buffer"
tracepoint, touch_buffer() called from __nilfs_get_folio_block() causes a
NULL pointer dereference, or a general protection fault when KASAN is
enabled.
This happens because since the tracepoint was added in touch_buffer(), it
references the dev_t member bh->b_bdev->bd_dev regardless of whether the
buffer head has a pointer to a block_device structure. In the current
implementation, the block_device structure is set after the function
returns to the caller.
Here, touch_buffer() is used to mark the folio/page that owns the buffer
head as accessed, but the common search helper for folio/page used by the
caller function was optimized to mark the folio/page as accessed when it
was reimplemented a long time ago, eliminating the need to call
touch_buffer() here in the first place.
So this solves the issue by eliminating the touch_buffer() call itself.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: sch_sfq: move the limit validation
It is not sufficient to directly validate the limit on the data that
the user passes as it can be updated based on how the other parameters
are changed.
Move the check at the end of the configuration update process to also
catch scenarios where the limit is indirectly updated, for example
with the following configurations:
tc qdisc add dev dummy0 handle 1: root sfq limit 2 flows 1 depth 1
tc qdisc add dev dummy0 handle 1: root sfq limit 2 flows 1 divisor 1
This fixes the following syzkaller reported crash:

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."

Bytes 40-65535 of 65536 are uninitialized
Memory access of size 65536 starts at ffff888045a40000
This happens, because we're copying a 'struct btrfs_data_container' back
to user-space. This btrfs_data_container is allocated in
'init_data_container()' via kvmalloc(), which does not zero-fill the
memory.
Fix this by using kvzalloc() which zeroes out the memory on allocation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix i_data_sem unlock order in ext4_ind_migrate()
Fuzzing reports a possible deadlock in jbd2_log_wait_commit.
This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to require
synchronous updates because the file descriptor is opened with O_SYNC.
This can lead to the jbd2_journal_stop() function calling
jbd2_might_wait_for_commit(), potentially causing a deadlock if the
EXT4_IOC_MIGRATE call races with a write(2) system call.
This problem only arises when CONFIG_PROVE_LOCKING is enabled. In this
case, the jbd2_might_wait_for_commit macro locks jbd2_handle in the
jbd2_journal_stop function while i_data_sem is locked. This triggers
lockdep because the jbd2_journal_start function might also lock the same
jbd2_handle simultaneously.
Found by Linux Verification Center (linuxtesting.org) with syzkaller.

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:
nilfs2: fix null-ptr-deref in block_dirty_buffer tracepoint
When using the "block:block_dirty_buffer" tracepoint, mark_buffer_dirty()
may cause a NULL pointer dereference, or a general protection fault when
KASAN is enabled.
This happens because, since the tracepoint was added in
mark_buffer_dirty(), it references the dev_t member bh->b_bdev->bd_dev
regardless of whether the buffer head has a pointer to a block_device
structure.
In the current implementation, nilfs_grab_buffer(), which grabs a buffer
to read (or create) a block of metadata, including b-tree node blocks,
does not set the block device, but instead does so only if the buffer is
not in the "uptodate" state for each of its caller block reading
functions. However, if the uptodate flag is set on a folio/page, and the
buffer heads are detached from it by try_to_free_buffers(), and new buffer
heads are then attached by create_empty_buffers(), the uptodate flag may
be restored to each buffer without the block device being set to
bh->b_bdev, and mark_buffer_dirty() may be called later in that state,
resulting in the bug mentioned above.
Fix this issue by making nilfs_grab_buffer() always set the block device
of the super block structure to the buffer head, regardless of the state
of the buffer's uptodate flag.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnilfs2: fix null-ptr-deref in block_dirty_buffer tracepoint\n\nWhen using the \"block:block_dirty_buffer\" tracepoint, mark_buffer_dirty()\nmay cause a NULL pointer dereference, or a general protection fault when\nKASAN is enabled.\n\nThis happens because, since the tracepoint was added in\nmark_buffer_dirty(), it references the dev_t member bh-\u003eb_bdev-\u003ebd_dev\nregardless of whether the buffer head has a pointer to a block_device\nstructure.\n\nIn the current implementation, nilfs_grab_buffer(), which grabs a buffer\nto read (or create) a block of metadata, including b-tree node blocks,\ndoes not set the block device, but instead does so only if the buffer is\nnot in the \"uptodate\" state for each of its caller block reading\nfunctions. However, if the uptodate flag is set on a folio/page, and the\nbuffer heads are detached from it by try_to_free_buffers(), and new buffer\nheads are then attached by create_empty_buffers(), the uptodate flag may\nbe restored to each buffer without the block device being set to\nbh-\u003eb_bdev, and mark_buffer_dirty() may be called later in that state,\nresulting in the bug mentioned above.\n\nFix this issue by making nilfs_grab_buffer() always set the block device\nof the super block structure to the buffer head, regardless of the state\nof the buffer\u0027s uptodate flag."
