In the Linux kernel, the following vulnerability has been resolved: btrfs: reject root items with drop_progress and zero drop_level [BUG] When recovering relocation at mount time, merge_reloc_root() and btrfs_drop_snapshot() both use BUG_ON(level == 0) to guard against an impossible state: a non-zero drop_progress combined with a zero drop_level in a root_item, which can be triggered: ------------[ cut here ]------------ kernel BUG at fs/btrfs/relocation.c:1545!

[CAUSE] A non-zero drop_progress.objectid means an interrupted btrfs_drop_snapshot() left a resume point on disk, and in that case drop_level must be greater than 0 because the checkpoint is only saved at internal node levels. Although this invariant is enforced when the kernel writes the root item, it is not validated when the root item is read back from disk. That allows on-disk corruption to provide an invalid state with drop_progress.objectid != 0 and drop_level == 0. When relocation recovery later processes such a root item, merge_reloc_root() reads drop_level and hits BUG_ON(level == 0). The same invalid metadata can also trigger the corresponding BUG_ON() in btrfs_drop_snapshot(). [FIX] Fix this by validating the root_item invariant in tree-checker when reading root items from disk: if drop_progress.objectid is non-zero, drop_level must also be non-zero. Reject such malformed metadata with -EUCLEAN before it reaches merge_reloc_root() or btrfs_drop_snapshot() and triggers the BUG_ON. After the fix, the same corruption is correctly rejected by tree-checker and the BUG_ON is no longer triggered.

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)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

    The bug is reproducible on 7.0.0-rc2-next-20260310 with our dynamic     metadata fuzzing tool that corrupts btrfs metadata at runtime.

    [CAUSE]     A non-zero drop_progress.objectid means an interrupted     btrfs_drop_snapshot() left a resume point on disk, and in that case     drop_level must be greater than 0 because the checkpoint is only     saved at internal node levels.

    Although this invariant is enforced when the kernel writes the root     item, it is not validated when the root item is read back from disk.
    That allows on-disk corruption to provide an invalid state with     drop_progress.objectid != 0 and drop_level == 0.

    When relocation recovery later processes such a root item,     merge_reloc_root() reads drop_level and hits BUG_ON(level == 0). The     same invalid metadata can also trigger the corresponding BUG_ON() in     btrfs_drop_snapshot().

    [FIX]     Fix this by validating the root_item invariant in tree-checker when     reading root items from disk: if drop_progress.objectid is non-zero,     drop_level must also be non-zero. Reject such malformed metadata with
    -EUCLEAN before it reaches merge_reloc_root() or btrfs_drop_snapshot()     and triggers the BUG_ON.

    After the fix, the same corruption is correctly rejected by tree-checker     and the BUG_ON is no longer triggered.

    The bug is reproducible on 7.0.0-rc2-next-20260310 with our dynamic     metadata fuzzing tool that corrupts btrfs metadata at runtime.

    [CAUSE]     A non-zero drop_progress.objectid means an interrupted     btrfs_drop_snapshot() left a resume point on disk, and in that case     drop_level must be greater than 0 because the checkpoint is only     saved at internal node levels.

    Although this invariant is enforced when the kernel writes the root     item, it is not validated when the root item is read back from disk.
    That allows on-disk corruption to provide an invalid state with     drop_progress.objectid != 0 and drop_level == 0.

    When relocation recovery later processes such a root item,     merge_reloc_root() reads drop_level and hits BUG_ON(level == 0). The     same invalid metadata can also trigger the corresponding BUG_ON() in     btrfs_drop_snapshot().

    [FIX]     Fix this by validating the root_item invariant in tree-checker when     reading root items from disk: if drop_progress.objectid is non-zero,     drop_level must also be non-zero. Reject such malformed metadata with
    -EUCLEAN before it reaches merge_reloc_root() or btrfs_drop_snapshot()     and triggers the BUG_ON.

    After the fix, the same corruption is correctly rejected by tree-checker     and the BUG_ON is no longer triggered.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For Debian 11 bullseye, these problems have been fixed in version     6.1.170-1~deb11u1.

    We recommend that you upgrade your linux-6.1 packages.

    For the detailed security status of linux-6.1 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/linux-6.1

    Further information about Debian LTS security advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://wiki.debian.org/LTS     Attachment:

Tenable has extracted the preceding description block directly from the Debian 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - btrfs: reject root items with drop_progress and zero drop_level [BUG] When recovering relocation at mount     time, merge_reloc_root() and btrfs_drop_snapshot() both use BUG_ON(level == 0) to guard against an     impossible state: a non-zero drop_progress combined with a zero drop_level in a root_item, which can be     triggered: ------------[ cut here ]------------ kernel BUG at fs/btrfs/relocation.c:1545!

[CAUSE] A non-zero     drop_progress.objectid means an interrupted btrfs_drop_snapshot() left a resume point on disk, and in that     case drop_level must be greater than 0 because the checkpoint is only saved at internal node levels.
    Although this invariant is enforced when the kernel writes the root item, it is not validated when the     root item is read back from disk. That allows on-disk corruption to provide an invalid state with     drop_progress.objectid != 0 and drop_level == 0. When relocation recovery later processes such a root     item, merge_reloc_root() reads drop_level and hits BUG_ON(level == 0). The same invalid metadata can also     trigger the corresponding BUG_ON() in btrfs_drop_snapshot(). [FIX] Fix this by validating the root_item     invariant in tree-checker when reading root items from disk: if drop_progress.objectid is non-zero,     drop_level must also be non-zero. Reject such malformed metadata with -EUCLEAN before it reaches     merge_reloc_root() or btrfs_drop_snapshot() and triggers the BUG_ON. After the fix, the same corruption is     correctly rejected by tree-checker and the BUG_ON is no longer triggered. (CVE-2026-43046)

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

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 6.1.170-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

    Further information about Debian Security Advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://www.debian.org/security/
