Unity Linux 20.1050e Security Update: kernel (UTSA-2026-006739)

medium Nessus Plugin ID 305382

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-2026-006739 advisory.

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

 scsi: qla4xxx: Prevent a potential error pointer dereference

 The qla4xxx_get_ep_fwdb() function is supposed to return NULL on error, but qla4xxx_ep_connect() returns error pointers. Propagating the error pointers will lead to an Oops in the caller, so change the error pointers to NULL.

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.
