CVE-2026-89766

A flaw was found in the Linux kernel. A local attacker could exploit a race condition in the pidfd subsystem, specifically within the PIDFDGETNAMESPACE ioctls. This vulnerability occurs because the system does not properly hold a lock execupdatelock during credential checks. This allows an attack...
