CVE-2023-53041

Kernel warning via locked abort-path completion

Published May 2, 2025 · Updated May 23, 2026

Improper locking in the Linux kernel qla2xxx driver allows local users to trigger a kernel warning during controller removal. In qla2x00_abort_srb, command completion runs while the abort-path lock remains held during driver unload, reaching DMA cleanup in the locked context. Reachability requires the qla2xxx driver and controller removal; the published trace establishes a warning and availability impact, not data access or modification.
