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-2024:0685-1 advisory.

This update for the Linux Kernel 5.14.21-150500_55_28 fixes several issues.

The following security issues were fixed:

- CVE-2023-4921: Fixed a use-after-free vulnerability in the QFQ network scheduler which could be exploited to achieve local privilege escalation (bsc#1215300).
- CVE-2023-51780: Fixed a use-after-free in do_vcc_ioctl in net/atm/ioctl.c, because of a vcc_recvmsg race condition (bsc#1218733).

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_14_21-150500_55_28-default package.
