CVE-2024-53125

Local privilege escalation via stale eBPF subregister state

Published Dec 4, 2024 · Updated Aug 5, 2026

Verifier state corruption in Linux 5.10 through 6.11.5 allows local users to gain kernel privileges via a crafted eBPF program. In sync_linked_regs(), range propagation overwrites the subreg_def marker, so mark_insn_zext() omits required zero-extension and the JIT uses attacker-controlled upper bits. Reachability requires unprivileged BPF access or a delegated BPF token; exploitation enables kernel reads, writes, privilege escalation, or a panic.
