CVE-2024-42285Network attack vector

Kernel memory corruption via premature CM ID teardown

Published Aug 17, 2024 · Updated Aug 5, 2026

Use-after-free in the Linux RDMA/iWARP connection manager allows remote attackers to corrupt kernel memory during CM ID teardown. rdma_destroy_id() frees the CM ID and its rdma_id_private while cm_work_handler() can still process queued work through the freed private structure. Reachability requires the iWARP RDMA connection-management path; the published record does not distinguish code execution from a host crash.
