"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: stm32-dcmipp: Return queued buffers on start_streaming() failure\n\nThe vb2 framework hands buffers to the driver via buf_queue() before\ncalling start_streaming(). If start_streaming() returns an error\nwithout first returning those buffers via vb2_buffer_done(),\nvb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued\nbuffers leak.\n\ndcmipp_bytecap_start_streaming() returned -EINVAL when the source\nsubdevice could not be resolved from the media graph, before\npm_runtime_resume_and_get() and media_pipeline_start() had been called.\nThe remaining error paths already converge on the err_buffer_done\nlabel, which calls dcmipp_bytecap_all_buffers_done(...,\nVB2_BUF_STATE_QUEUED). Jump to that label directly: the intermediate\nerr_pm_put / err_media_pipeline_stop labels are skipped, which is\ncorrect because nothing they would undo has happened yet.\n\nThis mirrors the uvcvideo fix in commit 4cf3b6fd54eb (\"media: uvcvideo:\nReturn queued buffers on start_streaming() failure\")."
