The EDID block index is driven by the device-supplied extension\ncount, so a malicious virtio-gpu backend can advertise a large size\ntogether with a high block count and read far past the array into adjacent\nkernel memory, which is then surfaced in the parsed EDID (an out-of-bounds\nread / info leak).\n\nAlso reject any read whose end exceeds the size of the edid array.\nConforming EDID responses stay within the array and are unaffected.","state":0,"publishedAt":"2026-08-10T12:01:24.835+00:00","modifiedAt":"2026-10-19T20:58:58.229+00:00","affected":[{"ecosystem":"Vendor
