  "details": "In the Linux kernel, the following vulnerability has been resolved:  media: sun4i-csi: Return queued buffers on start_streaming() failure  The vb2 framework hands buffers to the driver via buf_queue() before calling start_streaming().  If start_streaming() returns an error without first returning those buffers via vb2_buffer_done(), vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued buffers leak.  sun4i_csi_start_streaming() returned -EINVAL when no matching CSI format could be found, before any setup (scratch buffer allocation, pipeline start) had been performed.  The remaining error paths already converge on the err_clear_dma_queue label, which calls return_all_buffers(..., VB2_BUF_STATE_QUEUED) under csi-\u003eqlock.  Jump to that label directly: the intermediate err_disable_device / err_disable_pipeline / err_free_scratch_buffer labels are skipped, which is correct because nothing they would undo has happened yet.  This mirrors the uvcvideo fix in commit 4cf3b6fd54eb (\"media: uvcvideo: Return queued buffers on start_streaming() failure\").",
