Unity Linux 20.1050a Security Update: kernel (UTSA-2026-146613)

high Nessus Plugin ID 373192

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-2026-146613 advisory.

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

orangefs: skip leading spaces before parsing client debug masks

orangefs_prepare_cdm_array() sizes each client debug keyword buffer with strcspn(cds_head, ), but then parses the keyword with %s. The %s conversion skips leading whitespace, while strcspn() does not.

If a client debug entry starts with a space, the allocation can be sized for an empty keyword while sscanf() copies the following non-empty token.
This can write past the end of the allocated keyword buffer.

Skip leading spaces before computing the keyword length so the allocation matches the string parsed by sscanf().

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.

Solution

Update the affected kernel package.
