Summary
Security update for runc
Severity
Low
Notes
Title of the patch: Security update for runc
Description of the patch: This update for runc fixes the following issues: 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: * Various integration test improvements. * 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.

Versions 1.0.0-rc3 through 1.2.7, 1.3.0-rc.1 through 1.3.2, and 1.4.0-rc.1 through 1.4.0-rc.2, due to insufficient checks when bind-mounting `/dev/pts/$n` to `/dev/console` inside the container, an attacker can trick runc into bind-mounting paths which would normally be made read-only or be masked onto a path that the attacker can write to. This attack is very similar in concept and application to CVE-2025-31133, except that it attacks a similar vulnerability in a different target (namely, the bind-mount of `/dev/pts/$n` to `/dev/console` as configured for all containers that allocate a console). This happens after `pivot_root(2)`, so this cannot be used to write to host files directly -- however, as with CVE-2025-31133, this can load to denial of service of the host or a container breakout by providing the attacker with a writable copy of `/proc/sysrq-trigger` or `/proc/sys/kernel/core_pattern` (respectively). This issue is fixed in versions 1.2.8, 1.3.3 and 1.4.0-rc.3.",

This issue is not exploitable under Docker, because Docker creates a top-level read-only layer that masks any malicious /dev  symlink present in the container image - unlike some other Linux container tooling, whose higher-level runtimes built on runc remain exposed to exploitation via a malicious image.
