SUSE SLES12 Security Update : runc (SUSE-SU-2026:3428-2)

medium Nessus Plugin ID 334720

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-2026:3428-2 advisory.

 Update to 1.3.6.

 - CVE-2026-41579: malicious image with a `/dev` symlink can trigger limited host filesystem integrity violations (bsc#1268275).

 Other updates and bugfixes:

 - Version 1.3.6:
 * When masking directories with `maskPaths`, runc will now re- use a single `tmpfs` instance (which is not writeable) to reduce the number `tmpfs` superblocks that need to be reaped when containers die (in particular, Kubernetes applies masks to per-CPU sysfs directories which get expensive quickly).
 - Version 1.3.5:
 * Recursive atime-related mount flags (rrelatime et al.) are now applied properly.
 * PR #4757 caused a regression that resulted in spurious cannot start a container that has stopped errors when running runc create and has thus been reverted.
 * Updated builds to Go 1.25, libseccomp v2.6.0.
 * Minor signing keyring updates.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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 runc package.
