Synopsis

Description

The remote SUSE Linux SLES12 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:02676-1 advisory.

This update for the Linux Kernel 4.12.14-122_258 fixes several issues.

The following security issues were fixed:

- CVE-2025-37797: net_sched: hfsc: Fix a UAF vulnerability in class handling (bsc#1245793).
- CVE-2025-37752: net_sched: sch_sfq: move the limit validation (bsc#1245776).

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.
