Another issue\nis that a resource name could be a non printable bytearray and we cannot\nassume to be ASCII coded.\n\nThe log functionality is probably never being hit when DLM is used in\nnormal way and no debug logging is enabled. The null pointer dereference\ncan only occur on a new created lkb that does not have the resource\nassigned yet, it probably never hits the null pointer dereference but we\nshould be sure that other changes might not change this behaviour and we\nactually can hit the mentioned null pointer dereference.\n\nIn this patch we just drop the printout of the resource name, the lkb id\nis enough to make a possible connection to a resource name if this\nexists."

This matches the established scoring for CoCo host-to-guest issues in this subsystem (CVE-2026-64104, CVE-2026-52959, CVE-2025-38560).\nAC:L - The VMM implements the MapGPA handler and can deterministically fail it (non-zero status, or three STATUS_RETRY responses with an unchanged r11), forcing set_memory_decrypted() to return an error every time. No race, timing, or memory-layout condition outside the attacker\u0027s control is involved.\nPR:N - alloc_quote_buf() is reached only from tdx_guest_init() at module load during guest boot, so the host needs no credentials, account, or capability inside the guest at all. The hypervisor is entirely outside the guest\u0027s authentication domain in the TDX threat model.\nUI:N - The vulnerable path executes automatically when the tdx-guest driver initializes at boot; no guest user or administrator has to perform any action.\nS:C - Returning shared pages to the buddy allocator breaks the hardware-enforced TDX confidential-computing boundary, so data belonging to every other authority in the guest (all processes, containers, and the guest\u0027s protected TCB) becomes readable and writable by the hypervisor \u2014 impact well beyond the tdx-guest driver\u0027s own scope, consistent with CVE-2026-64104.\nC:H - The recycled pages alias host-visible shared memory, so anything the guest later places there \u2014 slab objects, page cache, anonymous user data, cryptographic keys \u2014 is exposed in plaintext to the untrusted host, giving a persistent, repeatedly refreshed arbitrary-read window into guest memory.\nI:H - The host can write those pages at will while they hold live kernel or user data, yielding an arbitrary-write primitive into whatever object currently occupies them (kernel structures with function pointers or list heads), which is leverageable for control-flow hijack inside the guest.\nA:H - Host modification of live kernel objects in the recycled pages, plus the private/shared state mismatch left by the failed conversion (#VE / EPT violation on kernel accesses), reliably produces guest kernel corruption and panic."

Specifically, sb_dqinfo(sb, type)-\u003edqi_priv is the\ndangling pointer.\n\nDuring the remounting process, the pointer dqi_priv is freed but is never\nset as null leaving it to be accessed.  Additionally, the read-only option\nfor remounting sets the DQUOT_SUSPENDED flag instead of setting the\nDQUOT_USAGE_ENABLED flags.  Moreover, later in the process of getting the\nnext quota, the function ocfs2_get_next_id is called and only checks the\nquota usage flags and not the quota suspended flags.\n\nTo fix this, I set dqi_priv to null when it is freed after remounting with\nread-only and put a check for DQUOT_SUSPENDED in ocfs2_get_next_id.\n\n[akpm@linux-foundation.org: coding-style cleanups]"

Despite the subsystem being a wireless PAN stack, the defect itself is in socket setup, not in frame processing.\nAC:H - The dangling pointer is only produced when `sk-\u003esk_prot-\u003ehash()` or `-\u003einit()` returns non-zero, but `raw_hash()`, `dgram_hash()` and `dgram_init()` all unconditionally `return 0` in every affected version (2.6.31\u20136.12) and the raw proto has no `.init`, so the error branch is unreachable and the attacker cannot influence it.\nPR:L - Creating a `SOCK_DGRAM` AF_IEEE802154 socket needs no capability at all, so any unprivileged local user reaches `ieee802154_create()`; note the `!net_eq(net, \u0026init_net)` guard means the call must be made in the initial netns, so user namespaces do not lower this further but also are not needed.\nUI:N - The attacker performs the whole sequence with a single `socket()` syscall from its own process. No victim action or interaction is involved.\nS:U - The freed `struct sock`/`struct dgram_sock` and the stale `sock-\u003esk` reference both live entirely within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Per the use-after-free rubric, a stale `sock-\u003esk` reference to a freed `dgram_sock` in the kmalloc-general caches would let an attacker reclaim the slab and read back attacker-shaped or leftover kernel data through subsequent socket operations.\nI:H - The same dangling reference would allow heap spraying of the reclaimed slot, giving control over function-pointer-bearing fields (`sk_prot`, `sk_destruct`, `sk_wq`) and thus a control-flow-hijack primitive rather than a mere data corruption.\nA:H - Any dereference of the freed `sock-\u003esk` would fault or corrupt the socket hash lists, producing an oops or panic; the rubric treats all use-after-free conditions as high availability impact even when only partially exploited."

An attacker needs local access to the machine to influence the boot environment and cause the kernel image to be loaded.\nAC:H - The `fail_free_cmdline` path is only reachable when `efi_parse_options()`\u0027s `allocate_pool` of a \u2264COMMAND_LINE_SIZE buffer fails, i.e. UEFI boot-services pool exhaustion \u2014 a firmware memory state the attacker cannot reliably influence, since the immediately preceding `efi_convert_cmdline()` allocation of comparable size already succeeded.\nPR:L - Reaching the stub requires a local foothold sufficient to influence the boot (boot entry/command line, chainloaded image, or a reboot on an embedded/kiosk arm64 device); no OS root or CAP_SYS_ADMIN in the running kernel is required.\nUI:N - No victim action is needed \u2014 the attacker with local access triggers the boot themselves, and the faulty path executes automatically inside the stub with no user prompt or interaction.\nS:U - The EFI stub already runs with full UEFI boot-services privilege by design, so corrupting the firmware pool does not cross into a different security authority; this is the standard \"same privilege domain\" case rather than a VM/IOMMU boundary escape.\nC:H - Firmware `FreePool()` on a stack address links stub stack memory into the boot-services free list, so that memory can later be handed to other allocations and read back; allocator-metadata corruption in the pre-boot environment is leverageable as an arbitrary-read primitive.\nI:H - Corrupting the UEFI pool allocator\u0027s free list yields attacker-influenced writes into fully privileged pre-boot memory, which is exploitable for control-flow hijack before any kernel hardening or Secure Boot lockdown is in effect.\nA:H - The invalid free hangs the boot outright on firmware that asserts on a bad pool signature (EDK2 DEBUG deadloop), and otherwise corrupts firmware heap state; the real `cmdline` pool allocation is additionally leaked on every occurrence."

It sets carrier ON\non start, but it doesn\u0027t implement .ndo_stop to set the carrier off.\nAnd it makes sense, because dummy doesn\u0027t really have a carrier.\nTherefore, while this device is unregistering, it\u0027s still easy to hit\nthe infinite loop in the skb_tx_hash() from the OVS datapath.  There\nmight be other drivers that do the same, but dummy by itself is\nimportant for the OVS ecosystem, because it is frequently used as a\npacket sink for tcpdump while debugging OVS deployments.  And when the\nissue is hit, the only way to recover is to reboot.\n\nFix that by also checking if the device is running.  The running\nstate is handled by the net core during unregistering, so it covers\nunregistering case better, and we don\u0027t really need to send packets\nto devices that are not running anyway.\n\nWhile only checking the running state might be enough, the carrier\ncheck is preserved.  The running and the carrier states seem disjoined\nthroughout the code and different drivers.  And other core functions\nlike __dev_direct_xmit() check both before attempting to transmit\na packet.  So, it seems safer to check both flags in OVS as well."

No local access is needed.\nAC:L - The `always_invalidate` module parameter defaults to true, so the defective branch is the default code path, and a single RTRS_MSG_WRITE with an unrecognized RNBD header type (or any ordinary write I/O completion) deterministically reaches `send_io_resp_imm()`. There is no race to win and no memory grooming required.\nPR:N - `rtrs_rdma_connect()` validates only RTRS_MAGIC, the protocol major version, and a UUID chosen by the client \u2014 the RTRS/RNBD wire protocol contains no authentication whatsoever. The `send_err_msg:` path into the vulnerable function is reachable before any block device has been opened on the session.\nUI:N - The server processes incoming RDMA work completions in a kernel workqueue with no operator involvement. No victim action is required beyond the storage server already running rnbd_server/rtrs_server.\nS:U - The dangling stack descriptor is consumed by kernel code and the resulting reads and crash occur within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The out-of-lifetime `ib_sge` supplies an unbounded address/length pair under `local_dma_lkey`; `rxe_mr_copy()` short-circuits to `rxe_mr_copy_dma()` before `mr_check_range()`, memcpy\u0027ing from that raw kernel virtual address into the outbound packet with no bounds check. Arbitrary kernel memory is therefore transmitted to the unauthenticated remote peer.\nI:H - The RDMA device is handed a work-request descriptor built entirely from out-of-lifetime memory, and the corrupted rkey response it produces is stored unvalidated by the peer (`clt_path-\u003erbufs[buf_id].rkey = le32_to_cpu(msg-\u003erkey)`), so subsequent server-to-client RDMA writes target an attacker-unintended memory region. Combined with the unchecked DMA-MR access primitive this is treated as a high integrity impact.\nA:H - The reported and reproduced consequence is a kernel page fault oops (`BUG: kernel NULL pointer dereference` in `rxe_mr_copy`/`memcpy_orig` from the `rxe_sender` workqueue), and failed posts additionally drive `close_path()`, tearing down the storage session. This is remotely and repeatedly triggerable."

The warning triggers from the legacy fallback stub.\n\nThat warning is bogus as the PCI/MSI layer knows whether a PCI/MSI parent\ndomain is associated with the device or not. There is a check for MSI-X,\nwhich has a legacy assumption. But that legacy fallback assumption is only\nvalid when legacy support is enabled, but otherwise the check should simply\nreturn -ENOTSUPP.\n\nLoongarch tripped over the same problem and blindly enabled legacy support\nwithout implementing the legacy fallbacks. There are weak implementations\nwhich return an error, so the problem was papered over.\n\nCorrect pci_msi_domain_supports() to evaluate the legacy mode and add\nthe missing supported check into the MSI enable path to complete it."

OTOH, the current code uses snd_card_free() at\ndisconnection, but this waits for the close of all used fds, hence it\ncan take long.  It eventually blocks the upper layer USB ioctls, which\nmay trigger a soft lockup.\n\nAn easy workaround is to replace snd_card_free() with\nsnd_card_free_when_closed().  This variant returns immediately while\nthe release of resources is done asynchronously by the card device\nrelease at the last close.\n\nThe loop of us122l-\u003emmap_count check is dropped as well.  The check is\nuseless for the asynchronous operation with *_when_closed()."

As Thomas suggested, timespec64_valid()\nonly check the timespec is valid, but not ensure that the time is\nin a valid range, so check it ahead using timespec64_valid_strict()\nin pc_clock_settime() and return -EINVAL if not valid.\n\nThere are some drivers that use tp-\u003etv_sec and tp-\u003etv_nsec directly to\nwrite registers without validity checks and assume that the higher layer\nhas checked it, which is dangerous and will benefit from this, such as\nhclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(),\nand some drivers can remove the checks of itself."

There is no network, adjacent, or remote-peer path into `pc_clock_settime()`.\nAC:L - A single syscall with e.g. `tv_nsec = 1000000000` or `tv_sec = -1` deterministically drives the unvalidated value into the driver callback \u2014 no race, no timing window, no memory-layout or victim-state dependency, and it can be repeated at will.\nPR:L - No capability check exists anywhere on the path; the sole gate is `FMODE_WRITE` on a PTP character device, which is routinely granted to non-root PTP/TSN daemons (linuxptp running with dropped privileges), containers, and appliance workloads in telecom, automotive and cloud deployments. An ordinary unprivileged user holding such a descriptor fully controls the trigger.\nUI:N - The attacker performs the whole sequence on a descriptor they opened themselves with one syscall. No mount, file open, or other action by another user is required.\nS:U - The corrupted state is the kernel\u0027s own PTP/posix-clock objects and the NIC\u0027s PHC managed by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is a missing input-validation check on a value flowing inward to hardware registers and time arithmetic; nothing is read out of bounds, no freed object is reused, and no kernel memory is copied back to userspace, so no read primitive exists.\nI:H - The attacker gains full, arbitrary control over the value programmed into the PTP hardware clock \u2014 the authoritative time base for all hardware timestamping on the interface, for PTP/gPTP synchronization of downstream nodes, and for TSN taprio/ETF gate schedules \u2014 and drivers such as `hclge_ptp_settime()`, `igb_ptp_settime_i210()` and `_rcar_gen4_ptp_settime()` commit it to registers with no checks of their own. Malicious modification of that specific state is a direct, serious integrity consequence for the impacted component, and it also drives undefined arithmetic (`timespec64_to_ns()` overflow, `timecounter_init()`, `do_div()` in `vsc9959_new_base_time()`) in code that assumed a validated input.\nA:H - Programming an out-of-range or negative time into the PHC produces a total, persistent loss of hardware timestamping, PTP synchronization and time-aware-shaper transmission on that interface \u2014 TSN gate schedules recomputed from the poisoned base never open, and the condition can be re-triggered at will so the service cannot recover. The unvalidated value additionally reaches out-of-spec hardware register writes and overflowing kernel time arithmetic on paths that assume validated input."

The consuming event, LPAR migration or CPU DLPAR, is a routine, expected operation on the affected PowerVM platform \u2014 indeed the vulnerable code exists solely to support it.\nPR:L - Only an unprivileged local user account is needed; `Documentation/arch/powerpc/vas-api.rst` states outright that \"No special privileges are needed to open the device,\" and distributions ship the nx-gzip node world-accessible because libnxz/zlib-NX is a userspace compression library. No capability check exists in `coproc_open()`, `coproc_ioc_tx_win_open()`, or `coproc_mmap()`.\nUI:N - No victim is lured into any action; the triggering Live Partition Mobility event is initiated externally by the hypervisor/HMC as routine platform maintenance, entirely outside any OS user\u0027s interaction with the attacker.\nS:U - The use-after-free is consumed inside the kernel and its impact stays within the kernel\u0027s own security authority; no hypervisor, IOMMU, or VM boundary is crossed.\nC:H - KASAN confirms an 8-byte slab-use-after-free read of a freed `vm_area_struct`, and reuse of that 168-byte mergeable-cache object lets the attacker place controlled data there and have the kernel dereference it, yielding kernel memory disclosure primitives well beyond a bounded leak.\nI:H - The freed object is not merely read \u2014 it is passed to `zap_page_range_single()`, so attacker-groomed `vm_mm`/`vm_start`/`vm_end` fields drive page-table teardown against an arbitrary address space while only the unrelated window owner\u0027s `mmap_lock` is held, giving a powerful controlled-pointer write/corruption primitive suitable for privilege escalation.\nA:H - The bug is a confirmed slab-use-after-free that produces a KASAN BUG/oops during partition migration, and unmapping another mm\u0027s pages without its `mmap_lock` readily leads to page-table corruption and kernel panic, taking down the entire LPAR at the worst possible moment."

No packet processing path reaches this function.\nAC:L - The failure path is deterministic, not a race: `socket(AF_INET6, SOCK_DGRAM, IPPROTO_ICMPV6)` fails with -EACCES for any user outside the default-empty `ping_group_range`, and can be repeated in a tight loop to spray and reclaim the freed `struct sock` reliably.\nPR:L - Any unprivileged local user can trigger the dangling pointer \u2014 `ping_init_sock()` returning -EACCES is precisely the unprivileged case, and the `BPF_CGROUP_RUN_PROG_INET_SOCK` rejection path applies to ordinary confined services. No capability is needed, and the SOCK_RAW variant is reachable via `unshare -Urn`.\nUI:N - Exploitation is entirely driven by the attacker\u0027s own syscalls; no victim action or interaction is required.\nS:U - The freed object and the corrupted state are both kernel networking structures within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The use-after-free lets an attacker reclaim the freed `struct sock` slab object with controlled data while a live `struct socket` still references it, enabling disclosure of kernel memory \u2014 the upstream KASAN report shows exactly such a UAF read in `__sock_gen_cookie()`.\nI:H - Control over the contents of the reclaimed `struct sock` (including embedded function pointers and `sk_prot`/`sk_destruct` fields) that are later dereferenced through the stale `sock-\u003esk` yields an arbitrary-write / control-flow-hijack primitive, the standard outcome for a kernel UAF on a sprayable slab object.\nA:H - Dereferencing the freed socket causes a kernel oops or panic, and the trigger is repeatable at will by an unprivileged user, making it a reliable local denial of service."

Delivery of the crafted image is via local/removable media, so the vector is Local.\nAC:L - The attacker fully controls the on-disk image and can deterministically set `stbl[i]` to a negative value; no race, no memory-layout guess, and no condition outside attacker control is involved. Any directory listing of the crafted directory reliably triggers the out-of-bounds access.\nPR:N - The attacker needs no privileges or account on the target system \u2014 they only supply a malicious JFS image (e.g. USB media), and the subsequent `readdir` requires nothing beyond ordinary directory read permission. JFS is `FS_REQUIRES_DEV` without `FS_USERNS_MOUNT`, so mounting is done by the victim/automounter rather than by the attacker.\nUI:R - The crafted filesystem must be mounted by a user or automounter (udisks/desktop automount on kiosks and workstations) before the directory can be read. That mount action is the required user interaction.\nS:U - The out-of-bounds read and write stay within the kernel\u0027s own memory and security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to 4 KB of kernel memory preceding the dtree metapage or the `jfs_inode_info` slab object is read and then emitted to userspace as directory entry names and inode numbers via `dir_emit()`, giving a directly harvestable disclosure of adjacent heap contents including potential pointers and secrets.\nI:H - The same unvalidated negative index flows into `add_missing_indices()`, which performs `d-\u003eindex = cpu_to_le32(add_index(...))` \u2014 a 4-byte out-of-bounds write at attacker-chosen negative offset \u2014 and stores the bad offset into the transaction linelock, corrupting adjacent kernel objects and journal metadata.\nA:H - Reading and writing up to 4 KB outside the metapage/slab object readily hits unmapped or poisoned memory, producing the KASAN-reported oops/panic seen by syzbot, and the stray write corrupts filesystem and journal state."

There was a WARN_ON(!new_page)\nbut it would still proceed to use the NULL pointer and then crash.\n\nThis case does seem somewhat rare but when the system is under memory\npressure it can happen. One case where I can duplicate this with some\nfrequency is when writing over a smbd share to a SATA HDD attached to an\nimx6q.\n\nSetting /proc/sys/vm/min_free_kbytes to higher values also seems to solve\nthe problem for my test case. But it still seems wrong that the fec driver\nignores the memory allocation error and can crash.\n\nThis commit handles the allocation error by dropping the current packet."

No local access is needed \u2014 a remote attacker\u0027s packets both create the memory pressure and drive the RX descriptor refill that dereferences NULL.\nAC:L - The attacker controls the triggering condition by controlling traffic volume: sustained flooding of a memory-constrained embedded target reliably drives page_pool allocation failures, and the fix\u0027s author reproduced the crash \"with some frequency\" using nothing but heavy network I/O. No specific memory layout or victim state outside the attacker\u0027s influence is required.\nPR:N - There is no authentication, capability check, or credential gate anywhere between frame arrival and fec_enet_update_cbd() \u2014 packet reception happens in softirq before any socket-level authorization. Unauthenticated flood traffic suffices to both induce memory pressure and supply the receive frames.\nUI:N - The RX path runs autonomously in NAPI/softirq context whenever frames arrive; no local user has to open a file, mount anything, or take any action for the dereference to occur.\nS:U - The fault and its consequences are confined to the kernel\u0027s own security authority on the affected host; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:N - The faulting access is a read of an unmapped low address (offsetof(struct net_iov, dma_addr) off a NULL netmem), which aborts immediately rather than returning data. No kernel memory contents, pointers, or freed-object data are disclosed to the attacker.\nI:N - There is no out-of-bounds or attacker-controlled write \u2014 the NULL store into rx_skb_info[] is a driver-internal field and execution aborts at the subsequent load before the bogus DMA address can be committed to hardware. No control-flow hijack or data modification primitive results.\nA:H - The NULL pointer dereference occurs in softirq/NAPI context, producing a fatal exception in interrupt context \u2014 a kernel panic (or an immediate panic via the preceding WARN_ON under panic_on_warn), taking down the entire device.

          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: musb: Fix hardware lockup on first Rx endpoint request\n\nThere is a possibility that a request\u0027s callback could be invoked from\nusb_ep_queue() (call trace below, supplemented with missing calls):\n\nreq-\u003ecomplete from usb_gadget_giveback_request\n\t(drivers/usb/gadget/udc/core.c:999)\nusb_gadget_giveback_request from musb_g_giveback\n\t(drivers/usb/musb/musb_gadget.c:147)\nmusb_g_giveback from rxstate\n\t(drivers/usb/musb/musb_gadget.c:784)\nrxstate from musb_ep_restart\n\t(drivers/usb/musb/musb_gadget.c:1169)\nmusb_ep_restart from musb_ep_restart_resume_work\n\t(drivers/usb/musb/musb_gadget.c:1176)\nmusb_ep_restart_resume_work from musb_queue_resume_work\n\t(drivers/usb/musb/musb_core.c:2279)\nmusb_queue_resume_work from musb_gadget_queue\n\t(drivers/usb/musb/musb_gadget.c:1241)\nmusb_gadget_queue from usb_ep_queue\n\t(drivers/usb/gadget/udc/core.c:300)\n\nAccording to the docstring of usb_ep_queue(), this should not happen:\n\n\"Note that @req\u0027s -\u003ecomplete() callback must never be called from within\nusb_ep_queue() as that can create deadlock situations.\"\n\nIn fact, a hardware lockup might occur in the following sequence:\n\n1. The gadget is initialized using musb_gadget_enable().\n2. Meanwhile, a packet arrives, and the RXPKTRDY flag is set, raising an\n   interrupt.\n3. If IRQs are enabled, the interrupt is handled, but musb_g_rx() finds an\n   empty queue (next_request() returns NULL). The interrupt flag has\n   already been cleared by the glue layer handler, but the RXPKTRDY flag\n   remains set.\n4. The first request is enqueued using usb_ep_queue(), leading to the call\n   of req-\u003ecomplete(), as shown in the call trace above.\n5. If the callback enables IRQs and another packet is waiting, step (3)\n   repeats. The request queue is empty because usb_g_giveback() removes the\n   request before invoking the callback.\n6. The endpoint remains locked up, as the interrupt triggered by hardware\n   setting the RXPKTRDY flag has been handled, but the flag itself remains\n   set.\n\nFor this scenario to occur, it is only necessary for IRQs to be enabled at\nsome point during the complete callback. This happens with the USB Ethernet\ngadget, whose rx_complete() callback calls netif_rx(). If called in the\ntask context, netif_rx() disables the bottom halves (BHs). When the BHs are\nre-enabled, IRQs are also enabled to allow soft IRQs to be processed. The\ngadget itself is initialized at module load (or at boot if built-in), but\nthe first request is enqueued when the network interface is brought up,\ntriggering rx_complete() in the task context via ioctl(). If a packet\narrives while the interface is down, it can prevent the interface from\nreceiving any further packets from the USB host.\n\nThe situation is quite complicated with many parties involved. This\nparticular issue can be resolved in several possible ways:\n\n1. Ensure that callbacks never enable IRQs. This would be difficult to\n   enforce, as discovering how netif_rx() interacts with interrupts was\n   already quite challenging and u_ether is not the only function driver.\n   Similar \"bugs\" could be hidden in other drivers as well.\n2. Disable MUSB interrupts in musb_g_giveback() before calling the callback\n   and re-enable them afterwars (by calling musb_{dis,en}able_interrupts(),\n   for example). This would ensure that MUSB interrupts are not handled\n   during the callback, even if IRQs are enabled. In fact, it would allow\n   IRQs to be enabled when releasing the lock. However, this feels like an\n   inelegant hack.\n3. Modify the interrupt handler to clear the RXPKTRDY flag if the request\n   queue is empty. While this approach also feels like a hack, it wastes\n   CPU time by attempting to handle incoming packets when the software is\n   not ready to process them.\n4. Flush the Rx FIFO instead of calling rxstate() in musb_ep_restart().\n   This ensures that the hardware can receive packets when there is at\n   least one request in the queue.

There\nare several conditions that must be fulfilled for the leak to occur:\n* an ICMPv6 packet indicating a change of the MTU for the path is received,\n  resulting in an exception dst being created\n* a TCP connection that uses the exception dst for routing packets must\n  start timing out so that TCP begins retransmissions\n* after the exception dst expires, the FIB6 garbage collector must not run\n  before TCP executes ip6_negative_advice() for the expired exception dst\n\nWhen TCP executes ip6_negative_advice() for an exception dst that has\nexpired and if no other socket holds a reference to the exception dst, the\nrefcount of the exception dst is 2, which corresponds to the increment\nmade by dst_init() and the increment made by the TCP socket for which the\nconnection is timing out. The refcount made by the socket is never\nreleased. The refcount of the dst is decremented in sk_dst_reset() but\nthat decrement is counteracted by a dst_hold() intentionally placed just\nbefore the sk_dst_reset() in ip6_negative_advice(). After\nip6_negative_advice() has finished, there is no other object tied to the\ndst. The socket lost its reference stored in sk_dst_cache and the dst is\nno longer in the exception table. The exception dst becomes a leaked\nobject.\n\nAs a result of this dst leak, an unbalanced refcount is reported for the\nloopback device of a net namespace being destroyed under kernels that do\nnot contain e5f80fcf869a (\"ipv6: give an IPv6 dev to blackhole_netdev\"):\nunregister_netdevice: waiting for lo to become free. Usage count = 2\n\nFix the dst leak by removing the dst_hold() in ip6_negative_advice(). The\npatch that introduced the dst_hold() in ip6_negative_advice() was\n92f1655aa2b22 (\"net: fix __dst_negative_advice() race\"). But 92f1655aa2b22\nmerely refactored the code with regards to the dst refcount so the issue\nwas present even before 92f1655aa2b22. The bug was introduced in\n54c1a859efd9f (\"ipv6: Don\u0027t drop cache route entry unless timer actually\nexpired.\") where the expired cached route is deleted and the sk_dst_cache\nmember of the socket is set to NULL by calling dst_negative_advice() but\nthe refcount belonging to the socket is left unbalanced.\n\nThe IPv4 version - ipv4_negative_advice() - is not affected by this bug.\nWhen the TCP connection times out ipv4_negative_advice() merely resets the\nsk_dst_cache of the socket while decrementing the refcount of the\nexception dst."

No local access is needed; a plain client connection to any public IPv6 TCP service suffices.\nAC:L - The attacker controls every condition: they choose when the PTB is sent (fixing the 10-minute expiry deadline) and when to go silent (driving the RTO schedule), and `tcp_write_timeout()` invokes `__dst_negative_advice()` before the retransmit\u0027s `sk_dst_check()`, so the first RTO after expiry leaks the dst near-deterministically; the attempt is freely repeatable across thousands of parallel connections.\nPR:N - Reaching the code requires only an established TCP/IPv6 connection to the victim plus an ICMPv6 error naming that flow \u2014 no credentials, capabilities, or local account are involved, and it works against unauthenticated public services.\nUI:N - The attacker initiates the connection and sends the ICMPv6 PTB themselves; the victim\u0027s kernel reacts autonomously via its retransmission timer with no action by any user or administrator.\nS:U - The leaked dst and the resulting resource exhaustion stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is an unbalanced refcount that over-holds an object; no memory is read out of bounds and no kernel data is exposed to the attacker.\nI:N - Over-holding a reference cannot corrupt memory or alter kernel or user data \u2014 the object is merely never freed, so there is no write or control-flow primitive.\nA:H - The orphaned dst permanently pins its `net_device` (`dst_init()` \u2192 `netdev_hold()`) and `inet6_dev`, so `unregister_netdevice` hangs forever (\"waiting for lo to become free\"), blocking the single global `cleanup_net` worker and thereby all network-namespace teardown host-wide \u2014 an unrecoverable hang on container hosts, compounded by unbounded kernel memory leakage under repeated triggering."

A malicious/compromised file server, or an off-path/MITM injector on the unsigned SMB1 stream, reaches it over the network.\nAC:L - The attacker controls both sides of the race: it can force repeated session teardowns (DFS referrals/failover, forced reconnects, multiuser tlink expiry) and can hold the SES_EXITING window open arbitrarily long by stalling the blocking SMB LOGOFF reply that `__cifs_put_smb_ses()` waits on before unlinking and freeing the session, while flooding oplock-break frames. Attempts are unlimited and require no condition outside the attacker\u0027s influence.\nPR:N - No credentials or privileges on the victim client are needed \u2014 the oplock-break frame is dispatched with no UID/session lookup and no signature validation, so any peer able to put bytes on the client\u0027s SMB connection triggers the walk. The attacking entity is the server side of an existing mount, which holds no privilege on the vulnerable system.\nUI:N - Exploitation only requires an already-established SMB1 mount, which in practice is persistent (fstab/autofs/systemd, embedded and industrial NAS deployments); a compromised or malicious server then attacks at a time of its choosing with no action by any local user.\nS:U - The use-after-free corrupts kernel heap objects within the same kernel security authority as the vulnerable code. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Use-after-free on `cifs_ses`/`cifs_tcon` structures lets the attacker reclaim the freed slab object with controlled content and have the kernel dereference and act on it, yielding a kernel-memory disclosure primitive. Session objects also hold credential material (auth keys, passwords), making leakage of highly sensitive data plausible.\nI:H - The UAF permits heap grooming so that attacker-shaped data occupies the freed session/tcon memory that is then written through and used for list and file-handle operations, giving a write/control-flow-hijack primitive. Per kernel CVSS guidance, memory corruption exploitable this way is scored High.\nA:H - Dereferencing freed session/tcon memory in the cifs demultiplex kernel thread readily produces an oops or panic, and the attacker can repeat it at will. Any kernel crash is High availability impact."
