CVE-2024-56602 is a Linux kernel memory-safety vulnerability in the ieee802154 networking subsystem. The flaw is in ieee802154_create(), where sock_init_data() attaches an allocated sk object to a sock object. If ieee802154_create() subsequently encounters an error, the allocated sk object is freed, but the sock object can retain a stale pointer to that freed sk object. This leaves a dangling pointer in the socket structure and creates a potential use-after-free condition. The fix clears the sk pointer in the sock object on the error path to prevent later dereference of freed memory.
