medium Nessus Plugin ID 280526

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-2025-992292 advisory.

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

 crypto: null - Use spin lock instead of mutex

 As the null algorithm may be freed in softirq context through af_alg, use spin locks instead of mutexes to protect the default null algorithm.

Solution
