CVE-2026-64010

Kernel memory corruption via unlocked LLCP transition

Published Jul 19, 2026 · Updated Jul 19, 2026

Use-after-free in affected Linux kernel NFC LLCP releases allows physically proximate attackers to corrupt memory during CC packet processing. The nfc_llcp_recv_cc() path moves a socket between connection lists without its socket lock, while llcp_sock_release() can concurrently unlink and free it. Exploitation requires NFC hardware and a concurrent socket release; the published record does not establish a specific outcome beyond unsafe reuse of the freed socket.
