Loading vulnerability…
CVE-2023-52735 affects the Linux kernel's BPF sockmap functionality. The sock_map_close, sock_map_destroy, and sock_map_unhash protocol callbacks can recursively invoke themselves, exhausting the kernel stack and causing a stack overflow. The fix detects and breaks recursive callback invocation, accepting a resource leak rather than allowing stack overflow.
