CVE-2026-72111

A flaw was found in the Linux kernel's BPF verifier. When processing a context load of an LSM hook return value, the markregs32range function incorrectly intersects new register bounds with stale ones, rather than replacing them. This can lead to a mismatch between the verifier's understanding of...
