Unity Linux 20.1050e Security Update: kernel (UTSA-2026-021581)

medium Nessus Plugin ID 315792

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-2026-021581 advisory.

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

bnxt: Do not read past the end of test names

Test names were being concatenated based on a offset beyond the end of the first name, which tripped the buffer overflow detection logic:

detected buffer overflow in strnlen [...] Call Trace:
bnxt_ethtool_init.cold+0x18/0x18

Refactor struct hwrm_selftest_qlist_output to use an actual array, and adjust the concatenation to use snprintf() rather than a series of strncat() calls.

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.
