      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: vidtv: fix nfeeds state corruption on start_streaming failure\n\nsyzbot reported a memory leak in vidtv_psi_service_desc_init [1].\n\nWhen vidtv_start_streaming() fails inside vidtv_start_feed(), the\nnfeeds counter is left incremented even though no feed was actually\nstarted. This corrupts the driver state: subsequent start_feed calls\nsee nfeeds > 1 and skip starting the mux, while stop_feed calls\neventually try to stop a non-existent stream.\n\nThis state corruption can also lead to memory leaks, since the mux\nand channel resources may be partially allocated during a failed\nstart_streaming but never cleaned up, as the stop path finds\ndvb->streaming == false and returns early.\n\nFix by decrementing nfeeds back when start_streaming fails, keeping\nthe counter in sync with the actual number of active feeds.\n\n[1]\nBUG: memory leak\nunreferenced object 0xffff888145b50820 (size 32):\n comm \"syz.0.17\", pid 6068, jiffies 4294944486\n backtrace (crc 90a0c7d4):\n  vidtv_psi_service_desc_init+0x74/0x1b0 drivers/media/test-drivers/vidtv/vidtv_psi.c:288\n  vidtv_channel_s302m_init+0xb1/0x2a0 drivers/media/test-drivers/vidtv/vidtv_channel.c:83\n  vidtv_channels_init+0x1b/0x40 drivers/media/test-drivers/vidtv/vidtv_channel.c:524\n  vidtv_mux_init+0x516/0xbe0 drivers/media/test-drivers/vidtv/vidtv_mux.c:518\n  vidtv_start_streaming drivers/media/test-drivers/vidtv/vidtv_bridge.c:194 [inline]\n  vidtv_start_feed+0x33e/0x4d0 drivers/media/test-drivers/vidtv/vidtv_bridge.c:239",
