CVE-2026-89970

A flaw was found in the nvmet-auth component of the Linux kernel. A timing issue during the cleanup of a Submission Queue SQ can lead to a use-after-free vulnerability. This occurs when a delayed authentication task attempts to access memory that has already been released or repurposed. An attack...

kernel: nvmet-auth: reject short AUTH_RECEIVE buffers

A flaw was found in the nvmet-auth component of the Linux kernel. A remote attacker, by sending a specially crafted AUTHRECEIVE buffer to an NVMe-oF NVM Express over Fabrics target with in-band authentication enabled, can trigger a heap out-of-bounds write. This vulnerability arises because the...
