CVE-2026-45927

In CVE-2026-45927, the Linux kernel BPF path bpf_map_get_info_by_fd caches the map hash regardless of the map’s frozen state, enabling a TOCTOU where a loader could verify a stale hash before freezing contents. The fix returns -EPERM if the map is not frozen when the hash is requested, ensuring t...
