CVE-2026-12234

The CVE affects Zephyr’s userspace networking verification on zsock_sendmsg/zsock_recvmsg. The issue is a TOCTOU double-fetch: the verifier snapshots struct net_msghdr, yet later re-reads the live user memory to bound the loop, allowing a race where msg_iovlen can be inflated after the shadow buf...
