27 Dec 2024 — In the Linux kernel, the following vulnerability has been resolved: tipc: Fix use-after-free of kernel socket in cleanup_bearer(). syzkaller reported a use-after-free of UDP kernel socket in cleanup_bearer() without repro. [0][1] When bearer_disable() calls tipc_udp_disable(), cleanup of the UDP kernel socket is deferred by work calling cleanup_bearer(). tipc_net_stop() waits for such works to finish by checking tipc_net(net)->wq_count. However, the work decrements the count too early before releasing the k... • https://git.kernel.org/stable/c/26abe14379f8e2fa3fd1bcf97c9a7ad9364886fe •
