Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4656-1 advisory.

 - CVE-2026-8674: reachable assert in `resolv/resolv_conf.c:update_from_conf` allows an attacker in a local network to trigger a process crash (bsc#1281297).
 - CVE-2026-86805: TOCTOU race condition in the dynamic loader allows local attackers to escalate privileges (bsc#1282509).

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 packages.
