CVE-2026-98088

The Linux kernel contains an out-of-bounds array read vulnerability within the scsi: mpt3sas driver. The issue occurs in the _base_assign_reply_queues() function because dev_to_node() can return NUMA_NO_NODE (-1) on systems lacking NUMA topology information (e.g., certain single-socket boards). T...
