medium Nessus Plugin ID 280613

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-2025-992239 advisory.

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

 scsi: scsi_dh_alua: Fix memleak for 'qdata' in alua_activate()

 If alua_rtpg_queue() failed from alua_activate(), then 'qdata' is not freed, which will cause following memleak:
