In the Linux kernel, the following vulnerability has been resolved: btrfs: fix transaction abort on set received ioctl due to item overflow If the set received ioctl fails due to an item overflow when attempting to add the BTRFS_UUID_KEY_RECEIVED_SUBVOL we have to abort the transaction since we did some metadata updates before. This means that if a user calls this ioctl with the same received UUID field for a lot of subvolumes, we will hit the overflow, trigger the transaction abort and turn the filesystem into RO mode. A malicious user could exploit this, and this ioctl does not even requires that a user has admin privileges (CAP_SYS_ADMIN), only that he/she owns the subvolume. Fix this by doing an early check for item overflow before starting a transaction. This is also race safe because we are holding the subvol_sem semaphore in exclusive (write) mode. A test case for fstests will follow soon.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098844 advisory.

Tenable has extracted the preceding description block directly from the SUSE 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: fix transaction abort on set received ioctl due to item overflow If the set received ioctl fails     due to an item overflow when attempting to add the BTRFS_UUID_KEY_RECEIVED_SUBVOL we have to abort the     transaction since we did some metadata updates before. This means that if a user calls this ioctl with the     same received UUID field for a lot of subvolumes, we will hit the overflow, trigger the transaction abort     and turn the filesystem into RO mode. A malicious user could exploit this, and this ioctl does not even     requires that a user has admin privileges (CAP_SYS_ADMIN), only that he/she owns the subvolume. Fix this     by doing an early check for item overflow before starting a transaction. This is also race safe because we     are holding the subvol_sem semaphore in exclusive (write) mode. A test case for fstests will follow soon.
    (CVE-2026-43359)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1594 advisory.
