CVE-2024-57834 is a null pointer dereference vulnerability in the Linux kernel's vidtv driver, specifically in the vidtv_mux_stop_thread function. The issue occurs if the dvb->mux pointer is not properly initialized during streaming startup, leading to a null pointer dereference when stopping the stream. This flaw was reported by syzbot and fixed by adjusting the initialization timing and adding checks before stopping the streaming thread.
