Description
A flaw was found in the Linux kernel's vidtv media driver. This vulnerability occurs because the vidtv_mux_push_si() function does not properly handle a NULL return value from vidtv_mux_get_pid_ctx(), which can happen if a PID context fails to allocate during initialization. An attacker could potentially trigger this NULL pointer dereference, leading to a general protection fault and causing a system crash, resulting in a denial of service.
Mitigation
No mitigation is specified in collected source.
