CVE-2024-41073Network attack vector

Kernel-memory corruption via NVMe discard retry double-free

Published Jul 29, 2024 · Updated Aug 5, 2026

Double-free in the Linux NVMe host driver allows remote attackers controlling an NVMe-oF peer to corrupt kernel memory during discard retries. nvme_cleanup_cmd frees a request's special payload but fails to clear RQF_SPECIAL_PAYLOAD, so a failed retry cleans the same allocation again. The required retry and cleanup sequence is controlled through the remote NVMe-oF peer, and the resulting corruption can crash or compromise the host.
