CVE-2026-80519

CVE-2026-80519 affects the Linux kernel OpenVPN module (ovpn) due to an incorrect ordering of reference cleanup in crypto completion callbacks. Specifically, the peer reference (which pins the netdev) is dropped before the callback finishes its own cleanup, allowing ovpn_crypto_key_slot_put to sc...

CVE-2026-74750

CVE-2026-74750 affects the Linux kernel's ovpn (OpenVPN) module . The root cause is that key slots are released via an RCU callback, which calls crypto_free_aead —a function that may sleep when an asynchronous or hardware crypto implementation has pending teardown work. Calling a sleeping functio...
