CVE-2026-90229

CVE-2026-90229 affects the nvme-apple platform driver in the Linux kernel. The admin queue is allocated via blk_mq_alloc_queue() but never destroyed on controller removal: blk_mq_exit_queue() and blk_sync_queue() are never called, leaving the timeout timer and work armed on a freed queue. This ca...

CVE-2026-90230

CVE-2026-90230 is a heap out-of-bounds read in the Linux kernel's NVMe target (nvmet) authentication path. The function nvmet_auth_negotiate() indexes a fixed idlist[60] array using host-supplied halen/dhlen fields (both u8, max 255) without validating the transfer length, allowing a malicious or...
