This leads to a general protection fault when\naccessing a near-NULL address.\n\nThe root cause is that vidtv_mux_pid_ctx_init() does not check the\nreturn value of vidtv_mux_create_pid_ctx_once() for PMT section PIDs.\nIf the allocation fails, the PID context is never created, but init\nreturns success. The subsequent vidtv_mux_push_si() call then gets\nNULL from vidtv_mux_get_pid_ctx() and crashes.\n\nFix both the root cause (add error check in vidtv_mux_pid_ctx_init\nfor PMT PIDs) and add defensive NULL checks in vidtv_mux_push_si for\nall vidtv_mux_get_pid_ctx() calls.\n\n[1]\nOops: general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] SMP KASAN PTI\nKASAN:
