CVE-2022-48711Network attack vector

Kernel code execution via TIPC stack overflow

Published Jun 20, 2024 · Updated Aug 5, 2026

Stack overflow in Linux kernel TIPC allows remote attackers to execute kernel code via crafted peer domain records. tipc_mon_rcv() trusts the member count in received domain_record structures and copies more than MAX_MON_DOMAIN entries onto the stack. Exploitation requires a reachable enabled TIPC bearer and the matching cluster net_id; success grants kernel control or crashes the host.
