CVE-2026-80843

Linux kernel IPsec transform (xfrm) subsystem is affected by a memory leak in xfrm_state_construct() . When an authentication algorithm with no sadb_alg_id (e.g., cmac(aes) ) is selected, attach_auth_trunc() allocates x->aalg but leaves x->props.aalgo at zero. The subsequent call to attach_...

EUVD-2026-70988

fastify versions = 4.0.0 and before 5.12.2 can route a malformed URL sent under one plugin prefix to the custom not-found handler of a different sibling plugin, and invoke it without the preHandler hook declared for that handler. The internal not-found router for encapsulated handlers dispatches...

CVE-2026-85184 @fastify/middie vulnerable to path-scoped middleware bypass via absolute-form request target

@fastify/middie versions = 9.1.0 and before 9.3.4 decide whether to run path-scoped middleware by matching against the raw request target, while the Fastify router resolves an absolute-form request target to its path before dispatching. Because the two layers evaluate different strings, a request...

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...

Linux Distros Unpatched Vulnerability : CVE-2026-14199
