CVE-2024-50026

Kernel crash via stale SCSI command pointer

Published Oct 21, 2024 · Updated May 11, 2026

Denial of service in the Linux kernel wd33c93 SCSI driver allows local users to trigger a kernel oops during device selection. In wd33c93_intr(), scsi_pointer is initialized from hostdata->connected while selection is still in progress, although that field is not yet valid; the current command resides in hostdata->selecting. Exploitation requires local low-privileged access and a system using the affected WD33C93 SCSI path, and the bounded consequence is a kernel crash that interrupts service.
