Synopsis

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

Description

The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2387-1 advisory.

This update for the Linux Kernel 5.3.18-24_37 fixes several issues.

The following security issues were fixed:

- CVE-2021-0512: Fixed a possible out-of-bounds write which could lead to local escalation of privilege with no additional execution privileges needed. (bsc#1187597)
- CVE-2021-23133: Fixed a race condition in the SCTP sockets that can lead to kernel privilege escalation from the context of a network service or an unprivileged process. (bsc#1185901)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel-livepatch-5_3_18-24_37-default package.
