In the Linux kernel, the following vulnerability has been resolved: ext4: always drain queued discard work in ext4_mb_release() While reviewing recent ext4 patch[1], Sashiko raised the following concern[2]: > If the filesystem is initially mounted with the discard option, > deleting files will populate sbi->s_discard_list and queue > s_discard_work. If it is then remounted with nodiscard, the > EXT4_MOUNT_DISCARD flag is cleared, but the pending s_discard_work is > neither cancelled nor flushed. [1] https://lore.kernel.org/r/20260319094545.19291-1-qiang.zhang@linux.dev/ [2] https://sashiko.dev/#/patchset/20260319094545.19291-1-qiang.zhang%40linux.dev The concern was valid, but it had nothing to do with the patch[1]. One of the problems with Sashiko in its current (early) form is that it will detect pre-existing issues and report it as a problem with the patch that it is reviewing. In practice, it would be hard to hit deliberately (unless you are a malicious syzkaller fuzzer), since it would involve mounting the file system with -o discard, and then deleting a large number of files, remounting the file system with -o nodiscard, and then immediately unmounting the file system before the queued discard work has a change to drain on its own. Fix it because it's a real bug, and to avoid Sashiko from raising this concern when analyzing future patches to mballoc.c.

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8668-1 advisory.

    Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly     validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use     this to construct a malicious NTFS image that, when mounted and operated on, could expose sensitive     information (kernel memory). (CVE-2023-45896)

    It was discovered that some AMD processors did not properly clear data in the floating point divider unit     during speculative execution. A local attacker could use this to expose sensitive information.
    (CVE-2025-54505)

    It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the     operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a     higher privilege level, resulting in privilege escalation. (CVE-2025-54518)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ext4: always drain queued discard work in ext4_mb_release() While reviewing recent ext4 patch[1], Sashiko     raised the following concern[2]: > If the filesystem is initially mounted with the discard option, >     deleting files will populate sbi->s_discard_list and queue > s_discard_work. If it is then remounted with     nodiscard, the > EXT4_MOUNT_DISCARD flag is cleared, but the pending s_discard_work is > neither cancelled     nor flushed. [1] https://lore.kernel.org/r/20260319094545.19291-1-qiang.zhang@linux.dev/ [2]     https://sashiko.dev/#/patchset/20260319094545.19291-1-qiang.zhang%40linux.dev The concern was valid, but     it had nothing to do with the patch[1]. One of the problems with Sashiko in its current (early) form is     that it will detect pre-existing issues and report it as a problem with the patch that it is reviewing. In     practice, it would be hard to hit deliberately (unless you are a malicious syzkaller fuzzer), since it     would involve mounting the file system with -o discard, and then deleting a large number of files,     remounting the file system with -o nodiscard, and then immediately unmounting the file system before the     queued discard work has a change to drain on its own. Fix it because it's a real bug, and to avoid Sashiko     from raising this concern when analyzing future patches to mballoc.c. (CVE-2026-43065)

Note that Nessus relies on the presence of the package as reported by the vendor.
