CVE-2024-56642

CVE-2024-56642 fixes a Linux kernel tipc use-after-free involving UDP sockets in cleanup_bearer(). The bug occurred when bearer_disable() leads to tipc_udp_disable(), and cleanup_bearer() decrements tipc_net(net)->wq_count too early, allowing a socket to be freed before its cleanup work comple...
