CVE-2026-23407

A flaw was found in AppArmor, a security module within the Linux kernel. A local user could exploit this vulnerability by providing a specially crafted Deterministic Finite Automaton DFA, a set of rules for pattern matching, to the verifydfa function. This malformed input causes the system to...
