Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2024:0418-1 advisory.

 - A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation. A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread. We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)

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

Update the affected kernel-livepatch-4_12_14-150100_197_160-default and / or kernel- livepatch-5_14_21-150500_55_39-default packages.
