An update that solves one vulnerability can now be installed.

## Description:

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:
* 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.
