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-2024:0995-1 advisory.

This update for the Linux Kernel 5.14.21-150500_13_5 fixes several issues.

The following security issues were fixed:

- CVE-2023-6531: Fixed a use-after-free flaw due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic()on the socket that the SKB is queued on (bsc#1218487).
- CVE-2023-46813: Fixed a local privilege escalation with user-space programs that have access to MMIO regions (bsc#1216898).
- CVE-2023-39191: Fixed a lack of validation of dynamic pointers within user-supplied eBPF programs that may have allowed an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code.
(bsc#1215863)
- CVE-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race condition in bt_sock_recvmsg (bsc#1218610).

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_13_5-rt package.
