update for runc","details":"This update for runc fixes the following issues:\n\nUpdate to 1.3.6.\n\n- CVE-2026-41579: malicious image with a `/dev` symlink can trigger limited host filesystem integrity violations\n  (bsc#1268275).\n\nOther updates and bugfixes:\n\n- Version 1.3.6:\n  * When masking directories with `maskPaths`, runc will now re- use a single `tmpfs` instance (which is not writeable)\n    to reduce the number `tmpfs` superblocks that need to be reaped when containers die (in particular, Kubernetes\n    applies masks to per-CPU sysfs directories which get expensive quickly).\n- Version 1.3.5:\n  * Recursive atime-related mount flags (rrelatime et al.) are now applied properly.\n  * PR #4757 caused a regression that resulted in spurious cannot start a container that has stopped errors when\n    running runc create and has thus been reverted.\n  * Updated builds to Go 1.25, libseccomp v2.6.0.\n  * Minor signing keyring updates.\n","affected":[{"package":{"name":"runc","ecosystem":"SUSE:Linux Enterprise High Performance Computing 15
