Loading vulnerability…
CVE-2024-26931 is a NULL pointer dereference vulnerability in the Linux kernel SCSI qla2xxx driver’s command-flush handling during cable removal. Under memory pressure, the driver may be unable to allocate an SRB for cable-pull error recovery, causing commands not to be flushed back to the SCSI layer. After memory becomes available, a subsequent cable-pull event can initiate another command flush; the driver can then dereference a NULL pointer while attempting to DMA-unmap the scatter-gather list.
