CVE-2026-23408

A flaw was found in AppArmor within the Linux kernel. This vulnerability involves a double free of the `ns_name` variable in the `aa_replace_profiles()` function. This can occur when `ns_name` is assigned from `ent->ns_name` without properly nulling out `ent->ns_name`, leading to it being freed twice. A local attacker could potentially exploit this memory corruption to cause a denial of service or other unpredictable system behavior.
