An update of the linux package has been released.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007386 advisory.

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

    f2fs: fix information leak in f2fs_move_inline_dirents()

    When converting an inline directory to a regular one, f2fs is leaking     uninitialized memory to disk because it doesn't initialize the entire     directory block.  Fix this by zero-initializing the block.

    This bug was introduced by commit 4ec17d688d74 (f2fs: avoid unneeded     initializing when converting inline dentry), which didn't consider the     security implications of leaking uninitialized memory to disk.

    This was found by running xfstest generic/435 on a KMSAN-enabled kernel.

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

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