CVE-2025-68341Network attack vector

Kernel memory corruption via nested XDP context clearing

Published Dec 23, 2025 · Updated Dec 23, 2025

Race condition in Linux 6.11 through 6.12.60 and 6.13 through 6.17.10 allows remote attackers to corrupt kernel memory via veth XDP traffic. In threaded-NAPI mode, concurrent veth_pool() calls share one task-level bpf_redirect_info context, and one call clears the no-direct-return state while another still uses it. An administrator must first configure veth XDP and threaded NAPI; subsequent unauthenticated traffic can expose or overwrite kernel memory, panic the host, or persistently interrupt packet processing.
