CVE-2026-72461

Vulnerability CVE-2026-72461 affects the Linux kernel with AppArmor: a refcount leak in updating the sk_ctx. Root cause: update_sk_ctx() transfers the plabel reference but also unconditionally releases it in the caller; the fix is to obtain a proper reference and avoid double-free. Affected compo...
