SUSE SLES12 Security Update : kernel (Live Patch 52 for SLE 12 SP5) (SUSE-SU-2024:1401-1)

high Nessus Plugin ID 193798

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 host has a package installed that is affected by a vulnerability as referenced in the SUSE- SU-2024:1401-1 advisory.

- A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)

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

Solution

Update the affected kgraft-patch-4_12_14-122_189-default package.
