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-2022:4027-1 advisory.

This update for the Linux Kernel 4.12.14-150000_150_95 fixes several issues.

The following security issues were fixed:

- CVE-2020-36557: Fixed a race condition between the VT_DISALLOCATE ioctl and closing/opening of ttys that could have led to a use-after-free (bnc#1201429).
- CVE-2020-36558: Fixed a race condition involving VT_RESIZEX which could lead to a NULL pointer dereference and general protection fault (bnc#1200910).

- CVE-2022-42703: Fixed use-after-free in mm/rmap.c related to leaf anon_vma double reuse (bnc#1204168).

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.
