{"id":"DEBIAN-CVE-2026-31585","details":"In the Linux kernel, the following vulnerability has been resolved:  media: vidtv: fix nfeeds state corruption on start_streaming failure  syzbot reported a memory leak in vidtv_psi_service_desc_init [1].  When vidtv_start_streaming() fails inside vidtv_start_feed(), the nfeeds counter is left incremented even though no feed was actually started. This corrupts the driver state: subsequent start_feed calls see nfeeds \u003e 1 and skip starting the mux, while stop_feed calls eventually try to stop a non-existent stream.  This state corruption can also lead to memory leaks, since the mux and channel resources may be partially allocated during a failed start_streaming but never cleaned up, as the stop path finds dvb-\u003estreaming == false and returns early.  Fix by decrementing nfeeds back when start_streaming fails, keeping the counter in sync with the actual number of active feeds.
