CVE-2023-54289

Service interruption via premature queue cleanup

Published Dec 30, 2025 · Updated Dec 30, 2025

NULL-pointer dereference in the Linux kernel qedf SCSI driver allows attackers to interrupt service via unspecified vectors. In qedf_alloc_global_queues(), an early allocation-error path calls qedf_free_global_queues() before qedf->global_queues exists, and the cleanup loop dereferences the NULL array. The failure occurs before any global queues are allocated; public sources do not identify an attacker-controlled trigger or required privileges.
