If a user then altered the V4L2 format to a smaller size, and a\nsubsequent run failed, rmi_f54_buffer_queue() would copy the stale,\nlarger payload size into the shrunken V4L2 buffer, causing a heap\nbuffer overflow.\n\nFix this by merging the 'abort' and 'error' labels into a single 'out'\nexit path, and ensuring that f54->report_size is always set to 0 on\nfailure by checking for error and zeroing the local report_size first."}], "lastModified": "2026-08-27T06:17:42.377", "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
