In the Linux kernel, the following vulnerability has been resolved: nilfs2: Fix potential block overflow that cause system hang When a user executes the FITRIM command, an underflow can occur when calculating nblocks if end_block is too small. Since nblocks is of type sector_t, which is u64, a negative nblocks value will become a very large positive integer. This ultimately leads to the block layer function __blkdev_issue_discard() taking an excessively long time to process the bio chain, and the ns_segctor_sem lock remains held for a long period. This prevents other tasks from acquiring the ns_segctor_sem lock, resulting in the hang reported by syzbot in [1]. If the ending block is too small, typically if it is smaller than 4KiB range, depending on the usage of the segment 0, it may be possible to attempt a discard request beyond the device size causing the hang. Exiting successfully and assign the discarded size (0 in this case) to range->len. Although the start and len values in the user input range are too small, a conservative strategy is adopted here to safely ignore them, which is equivalent to a no-op; it will not perform any trimming and will not throw an error.

The remote Ubuntu 22.04 LTS / 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8497-1 advisory.

    It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer     operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in     the RxRPC networking subsystem when processing paged fragments. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43284, CVE-2026-43500, CVE-2026-45998,     CVE-2026-46000)

    It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when     handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43503, CVE-2026-46300)

    Qualys discovered that a race condition existed in the ptrace subsystem of the Linux kernel when     privileged processes are exiting. An unprivileged local attacker could use this issue to expose sensitive     information. (CVE-2026-46333)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a memory leak when handling     AppArmor notifications. A local attacker could use this to cause resource exhaustion. (CVE-2026-47326)

    (CVE-2026-47328)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained insufficient validation of     AppArmor notification responses. A local attacker could use this to allow crafted responses to be     processed. (CVE-2026-47329)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 used an uninitialized variable when     handling AppArmor notifications. A local attacker could use this to cause incorrect caching of data.
    (CVE-2026-47330)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a use- after-free (UAF) bug. A local     attacker could use this to cause memory corruption and, theoretically, arbitrary code execution.
    (CVE-2026-47331)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an out-of-bounds (OOB) read     when handling AppArmor notifications. A local attacker could use this to cause information disclosure of     kernel memory. (CVE-2026-47332)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained a out-of-bounds (OOB) read     when handling AppArmor notifications. A local attacker could use this to cause kernel memory corruption     and, theoretically, influence processing of AppArmor policies. (CVE-2026-47333)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained incorrect holding of locks     when handling AppArmor notifications. A local attacker could use this to cause a kernel panic or deadlock.
    (CVE-2026-47334)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a NULL pointer dereference when handling     AppArmor notifications. A local attacker could use this to cause a kernel panic. (CVE-2026-47335)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 used an uninitialized variable when handling     AppArmor AF_INET/AF_INET6 socket mediation. A local attacker could use this to influence processing of     fine- grained network socket mediation. (CVE-2026-47336)

    Tristan Madani and Trevor Lawrence have each independently discovered that Ubuntu Linux kernel 6.8, 6.17     and 7.0 contained a NULL pointer dereference when handling AppArmor network socket mediation. A local     attacker could use this to cause a kernel oops. (CVE-2026-47337)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8499-1 advisory.

    It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic     operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or     possibly escape a container. (CVE-2026-31431)

    It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer     operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in     the RxRPC networking subsystem when processing paged fragments. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43284, CVE-2026-43500, CVE-2026-45998,     CVE-2026-46000)

    It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when     handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43503, CVE-2026-46300)

    Qualys discovered that a race condition existed in the ptrace subsystem of the Linux kernel when     privileged processes are exiting. An unprivileged local attacker could use this issue to expose sensitive     information. (CVE-2026-46333)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a memory leak when handling     AppArmor notifications. A local attacker could use this to cause resource exhaustion. (CVE-2026-47326)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contain a NULL pointer dereference     when handling AppArmor notifications. A local attacker could use this to cause a kernel oops.
    (CVE-2026-47327)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an invalid free when     handling AppArmor notifications. A local attacker could use this to corrupt kernel memory.
    (CVE-2026-47328)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained insufficient validation of     AppArmor notification responses. A local attacker could use this to allow crafted responses to be     processed. (CVE-2026-47329)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 used an uninitialized variable when     handling AppArmor notifications. A local attacker could use this to cause incorrect caching of data.
    (CVE-2026-47330)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a use- after-free (UAF) bug. A local     attacker could use this to cause memory corruption and, theoretically, arbitrary code execution.
    (CVE-2026-47331)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained an out-of-bounds (OOB) read     when handling AppArmor notifications. A local attacker could use this to cause information disclosure of     kernel memory. (CVE-2026-47332)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained a out-of-bounds (OOB) read     when handling AppArmor notifications. A local attacker could use this to cause kernel memory corruption     and, theoretically, influence processing of AppArmor policies. (CVE-2026-47333)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8, 6.17 and 7.0 contained incorrect holding of locks     when handling AppArmor notifications. A local attacker could use this to cause a kernel panic or deadlock.
    (CVE-2026-47334)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 contained a NULL pointer dereference when handling     AppArmor notifications. A local attacker could use this to cause a kernel panic. (CVE-2026-47335)

    Tristan Madani discovered that Ubuntu Linux kernel 6.8 used an uninitialized variable when handling     AppArmor AF_INET/AF_INET6 socket mediation. A local attacker could use this to influence processing of     fine- grained network socket mediation. (CVE-2026-47336)

    Tristan Madani and Trevor Lawrence have each independently discovered that Ubuntu Linux kernel 6.8, 6.17     and 7.0 contained a NULL pointer dereference when handling AppArmor network socket mediation. A local     attacker could use this to cause a kernel oops. (CVE-2026-47337)

    In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: Avoid creating sub-     groups asynchronously The asynchronous creation of sub-groups by a delayed work could lead to a NULL     pointer dereference when the driver directory is removed before the work completes. The crash can be     easily reproduced with the following commands: # cd /sys/kernel/config/pci_ep/functions/pci_epf_test # for     i in {1..20}; do mkdir test && rmdir test; done BUG: kernel NULL pointer dereference, address:

As part of the discovery, after receiving an interrupt a work queue was scheduled     (which involved a work to be queued). Since the UNLOADING flag is set, the work item was not allocated and     the mapped memory had to be freed. The free occurred in interrupt context leading to system crash. Delay     the driver unload until the fabric scan is complete to avoid the crash. (CVE-2025-71235)

    In the Linux kernel, the following vulnerability has been resolved: nilfs2: Fix potential block overflow     that cause system hang When a user executes the FITRIM command, an underflow can occur when calculating     nblocks if end_block is too small. Since nblocks is of type sector_t, which is u64, a negative nblocks     value will become a very large positive integer. This ultimately leads to the block layer function
    __blkdev_issue_discard() taking an excessively long time to process the bio chain, and the ns_segctor_sem     lock remains held for a long period. This prevents other tasks from acquiring the ns_segctor_sem lock,     resulting in the hang reported by syzbot in [1]. If the ending block is too small, typically if it is     smaller than 4KiB range, depending on the usage of the segment 0, it may be possible to attempt a discard     request beyond the device size causing the hang. Exiting successfully and assign the discarded size (0 in     this case) to range->len. Although the start and len values in the user input range are too small, a     conservative strategy is adopted here to safely ignore them, which is equivalent to a no-op; it will not     perform any trimming and will not throw an error.

    In the Linux kernel, the following vulnerability has been resolved:

    mptcp: fix race in mptcp_pm_nl_flush_addrs_doit() (CVE-2026-23169)

    In the Linux kernel, the following vulnerability has been resolved: bus: fsl-mc: fix use-after-free in     driver_override_show() The driver_override_show() function reads the driver_override string without     holding the device_lock. However, driver_override_store() uses driver_set_override(), which modifies and     frees the string while holding the device_lock. This can result in a concurrent use-after-free if the     string is freed by the store function while being read by the show function. Fix this by holding the     device_lock around the read operation. (CVE-2026-23221)

    In the Linux kernel, the following vulnerability has been resolved: crypto: omap - Allocate     OMAP_CRYPTO_FORCE_COPY scatterlists correctly The existing allocation of scatterlists in     omap_crypto_copy_sg_lists() was allocating an array of scatterlist pointers, not scatterlist objects,     resulting in a 4x too small allocation. Use sizeof(*new_sg) to get the correct object size.

    Replace free_transport() with ksmbd_tcp_disconnect(). (CVE-2026-23228)

    In the Linux kernel, the following vulnerability has been resolved: crypto: virtio - Add spinlock     protection with virtqueue notification When VM boots with one virtio-crypto PCI device and builtin     backend, run openssl benchmark command with multiple processes, such as openssl speed -evp aes-128-cbc
    -engine afalg -seconds 10 -multi 32 openssl processes will hangup and there is error reported like this:
    virtio_crypto virtio0: dataq.0:id 3 is not a head! It seems that the data virtqueue need protection when     it is handled for virtio done notification. If the spinlock protection is added in virtcrypto_done_task(),     openssl benchmark with multiple processes works well. (CVE-2026-23229)

    In the Linux kernel, the following vulnerability has been resolved: smb: client: split cached_fid     bitfields to avoid shared-byte RMW races is_open, has_lease and on_list are stored in the same bitfield     byte in struct cached_fid but are updated in different code paths that may run concurrently. Bitfield     assignments generate byte read-modify-write operations (e.g. `orb $mask, addr` on x86_64), so updating one     flag can restore stale values of the others. A possible interleaving is: CPU1: load old byte (has_lease=1,     on_list=1) CPU2: clear both flags (store 0) CPU1: RMW store (old | IS_OPEN) -> reintroduces cleared bits     To avoid this class of races, convert these flags to separate bool fields. (CVE-2026-23230)

    In the Linux kernel, the following vulnerability has been resolved: romfs: check sb_set_blocksize() return     value romfs_fill_super() ignores the return value of sb_set_blocksize(), which can fail if the requested     block size is incompatible with the block device's configuration. This can be triggered by setting a loop     device's block size larger than PAGE_SIZE using ioctl(LOOP_SET_BLOCK_SIZE, 32768), then mounting a romfs     filesystem on that device. When sb_set_blocksize(sb, ROMBSIZE) is called with ROMBSIZE=4096 but the device     has logical_block_size=32768, bdev_validate_blocksize() fails because the requested size is smaller than     the device's logical block size. sb_set_blocksize() returns 0 (failure), but romfs ignores this and     continues mounting. The superblock's block size remains at the device's logical block size (32768). Later,     when sb_bread() attempts I/O with this oversized block size, it triggers a kernel BUG in folio_set_bh():
    kernel BUG at fs/buffer.c:1582! BUG_ON(size > PAGE_SIZE); Fix by checking the return value of     sb_set_blocksize() and failing the mount with -EINVAL if it returns 0. (CVE-2026-23238)

  - nilfs2: Fix potential block overflow that cause system hang When a user executes the FITRIM command, an     underflow can occur when calculating nblocks if end_block is too small. Since nblocks is of type sector_t,     which is u64, a negative nblocks value will become a very large positive integer. This ultimately leads to     the block layer function __blkdev_issue_discard() taking an excessively long time to process the bio     chain, and the ns_segctor_sem lock remains held for a long period. This prevents other tasks from     acquiring the ns_segctor_sem lock, resulting in the hang reported by syzbot in [1]. If the ending block is     too small, typically if it is smaller than 4KiB range, depending on the usage of the segment 0, it may be     possible to attempt a discard request beyond the device size causing the hang. Exiting successfully and     assign the discarded size (0 in this case) to range->len. Although the start and len values in the user     input range are too small, a conservative strategy is adopted here to safely ignore them, which is     equivalent to a no-op; it will not perform any trimming and will not throw an error.
