Unity Linux 20.1070e Security Update: kernel (UTSA-2025-986500)

high Nessus Plugin ID 268029

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-2025-986500 advisory.

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

 jfs: xattr: fix buffer overflow for invalid xattr

 When an xattr size is not what is expected, it is printed out to the kernel log in hex format as a form of debugging. But when that xattr size is bigger than the expected size, printing it out can cause an access off the end of the buffer.

 Fix this all up by properly restricting the size of the debug hex dump in the kernel log.

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.
