Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004463 advisory.

 An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A stall on CPU can occur because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1.

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.
