CVE-2025-38288

Kernel call-trace exposure via unsafe CPU lookup

Published Jul 10, 2025 · Updated May 11, 2026

Incorrect CPU identification in Linux allows local users to trigger a smartpqi kernel call trace through queued SCSI work. The pqi_scsi_queue_command path calls smp_processor_id() while preemption is enabled, causing the helper to emit an error and invoke dump_stack(). Reachability requires the smartpqi driver on a preemptible kernel; published records establish log exposure but not service interruption or further compromise.
