CVE-2024-36933Public exploit

Kernel data exposure and crash via header misrestore

Published May 30, 2024 · Updated Aug 5, 2026

Kernel packet-processing corruption in Linux allows local users to expose heap data, alter transmitted frames, or crash the host. In nsh_gso_segment(), restoring stale skb header offsets after inner segmentation leaves data and mac_header pointing into shifted buffers or the NSH header instead of the outer header. Reachability requires CAP_NET_RAW obtainable in a user and network namespace and a crafted layered GSO packet; consequences include heap-data emission, malformed frames, and kernel panic.
