CVE-2026-64319 — Linux: A malicious NVMe-oF initiator can craft a DHCHAP_REPLY message with a small transfer length
In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: validate reply message payload bounds against transfer length nvmet_auth_reply() accesses the variable-length rval[] array using attacker-controlled hl (hash length) and dhvlen (DH value length) fields without verifying they fit within the allocated buffer of tl bytes. A malicious NVMe-oF initiator can craft a DHCHAP_REPLY message with a small transfer length but large hl/dhvlen values, causing CVSSv3.1 9.1 (CRITICAL) · EPSS 17th percentile
