kernel: nvmet-auth: validate reply message payload bounds against transfer length

A flaw was found in the Linux kernel's nvmet-auth component. A remote attacker, by sending a specially crafted NVMe-oF NVMe over Fabrics authentication reply message, can cause an out-of-bounds read in the kernel's memory. This vulnerability, exploitable pre-authentication, can lead to the...

CVE-2026-80862

This Linux kernel vulnerability affects the nvme-tcp subsystem. The page_frag_cache is used to preallocate PDU buffers for preallocated block device requests, but since block devices are created in parallel threads, the cache is accessed in a thread-unsafe manner. This leads to incorrect refcount...
