CVE-2026-43473

CVE-2026-43473 affects the Linux kernel's mpi3mr SCSI driver. The vulnerability occurs when the driver cleans up resources and the reply/request queues are NULL due to memory being freed after a failed queue creation. The cleanup code may then dereference or mem-set freed memory, causing a system...
