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\nairspy_start_streaming() returned -ENODEV early when the USB device had\nbeen disconnected (s->udev == NULL) without returning any buffers that\nbuf_queue() had already accepted.  Take v4l2_lock first and jump to the\nexisting err_clear_bit label, which already drains s->queued_bufs via\nvb2_buffer_done(..., VB2_BUF_STATE_QUEUED) before unlocking.\n\nThis mirrors the uvcvideo fix in commit 4cf3b6fd54eb (\"media: uvcvideo:\nReturn queued buffers on start_streaming() failure\").","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/04344d0b4929caa94c0df72f767752aa0935ef5d","https://git.kernel.org/stable/c/122ce0c0af629a8765ddf1adf6fb85c6db3d47cb","https://git.kernel.org/stable/c/170fcc945bc094b1c956bf555c070692826a3eff","https://git.kernel.org/stable/c/73bd2779865372b1017d4f555b45270aa2d0d710","https://git.kernel.org/stable/c/877686a74ecdc93dcaee09dbac566e819059c9e7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68231","score":0.0022,"percentile":0.12571,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
