Since V4L2 buffers are allocated based on the size at\nstream start, changing the input while streaming could lead to a\nheap buffer overflow if the new size is larger than the allocated\nbuffers.\n\nPrevent this by blocking VIDIOC_S_INPUT with -EBUSY if the V4L2 queue\nis busy (streaming).","published":"2026-08-26T15:17:12.000Z","lastModified":"2026-08-27T06:17:42.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.0019,"percentile":0.08588,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.19%).
