CVE-2025-39860

CVE-2025-39860 – Linux kernel Bluetooth UAF in l2cap_sock_cleanup_listen() . The vulnerability arises from a race between bt_accept_dequeue() and l2cap_sock_cleanup_listen() where a socket could be freed while another path still holds a reference. The root cause is a race in the l2cap_sock_cleanu...

CVE-2025-39852

CVE-2025-39852: Linux kernel TCP stack IPv6 TCP-AO path leaks memory when tcp_v6_syn_recv_sock() exits on error due to missing error-handling cleanup. The linked Astra/OpenSUSE advisories confirm the fix adds inet_csk_prepare_forced_close() and tcp_done() (as in the IPv4 path) to ensure the new s...
