Unity Linux 20.1070e Security Update: kernel (UTSA-2026-005555)

medium Nessus Plugin ID 300361

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-2026-005555 advisory.

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

 coresight: trbe: remove cpuhp instance node before remove cpuhp state

 cpuhp_state_add_instance() and cpuhp_state_remove_instance() should be used in pairs. Or there will lead to the warn on cpuhp_remove_multi_state() since the cpuhp_step list is not empty.

 The following is the error log with 'rmmod coresight-trbe':
 Error: Removing state 215 which has instances left.
