  "details": "In the Linux kernel, the following vulnerability has been resolved:  media: vidtv: fix NULL pointer dereference in vidtv_channel_pmt_match_sections  syzbot reported a general protection fault in vidtv_psi_desc_assign [1].  vidtv_psi_pmt_stream_init() can return NULL on memory allocation failure, but vidtv_channel_pmt_match_sections() does not check for this. When tail is NULL, the subsequent call to vidtv_psi_desc_assign(\u0026tail-\u003edescriptor, desc) dereferences a NULL pointer offset, causing a general protection fault.  Add a NULL check after vidtv_psi_pmt_stream_init(). On failure, clean up the already-allocated stream chain and return.
