Unity Linux 20.1070a Security Update: kernel (UTSA-2025-380468)

high Nessus Plugin ID 267471

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-2025-380468 advisory.

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

 filelock: fix potential use-after-free in posix_lock_inode

 Light Hsieh reported a KASAN UAF warning in trace_posix_lock_inode().
 The request pointer had been changed earlier to point to a lock entry that was added to the inode's list. However, before the tracepoint could fire, another task raced in and freed that lock.

 Fix this by moving the tracepoint inside the spinlock, which should ensure that this doesn't happen.

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.
