Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2599-1 advisory.

The SUSE Linux Enterprise 15 SP2 RT kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:
