CVE-2026-45848

The CVE-2026-45848 issue affects the Linux kernel AppArmor component, where NULL sock or sock-sk can occur during socket setup/teardown, potentially causing a NULL pointer dereference and a kernel oops (DoS) for af_unix sockets. Root cause is dereferencing NULL during socket operations; impact is...
