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-2026:0487-1 advisory.

This update for the SUSE Linux Enterprise kernel 6.4.0-150700.7.3 fixes various security issues

The following security issues were fixed:

- CVE-2025-38111: net/mdiobus: Fix potential out-of-bounds read/write access (bsc#1249455).
- CVE-2025-38352: posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del() (bsc#1249205).

The following non security issue was fixed:

- bsc#1249241: fix addr_bit_set() issue on big-endian machines BITOP_BE32_SWIZZLE ought to be defined depending on the target's endianess, but the livepatch includes only the little-endian variant. Fix that.
(bsc#1249241 bsc#1256928).

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-6_4_0-150700_7_3-rt package.
