CVE-2026-53233

A flaw was found in the Linux kernel. A double-free vulnerability exists within the netdev_nl_bind_rx_doit() function, which is responsible for binding network device receive operations. This vulnerability arises when genlmsg_reply() consumes the socket buffer (skb), and the error handling path subsequently attempts to free the response (rsp) again, resulting in a double-free. This could allow a local attacker to cause a denial of service (DoS) or potentially execute arbitrary code.
