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...

CVE-2026-23403

A flaw was found in AppArmor within the Linux kernel. This vulnerability, located in the verifyheader function, causes a memory leak by incorrectly handling namespace strings when multiple security profiles are processed. This can lead to a gradual depletion of system memory, potentially impactin...

EUVD-2026-17831

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix memory leak in verifyheader The function sets ns = NULL on every call, leaking the namespace string allocated in previous iterations when multiple profiles are unpacked. This also breaks namespace consistency checki...

CVE-2026-23407

The CVE-2026-23407 issue affects the Linux kernel AppArmor DFA verification. The root cause is a missing bounds check on DEFAULT_TABLE in verify_dfa(), which can read k = DEFAULT_TABLE[j] as an index without validation when traversing the differential encoding chain, allowing out-of-bounds reads/...

CVE-2026-23403

CVE-2026-23403 concerns the AppArmor memory leak in Linux kernel’s verify_header. The issue arises because a function sets *ns = NULL on every call, leaking the previously allocated namespace string across successive profile unpackings and causing namespace consistency checks to see NULL for *ns....
