Loading vulnerability…
CVE-2024-26931 is a NULL pointer dereference in the Linux kernel qla2xxx Fibre Channel SCSI driver’s command-flush handling during remote-session teardown following a cable pull. Under memory pressure, the driver can fail to allocate an SRB needed for error recovery and fail to flush outstanding commands back to the SCSI layer. A later cable-pull event can initiate another flush after upper layers have modified the affected SCSI command, causing qla2xxx to dereference a NULL pointer while attempting to DMA-unmap the command SGL. The fix ensures commands are flushed back during session teardown.
