The software writes configuration data to a fixed-size array without checking if the array index exceeds its maximum size of EC_MAXFMMU entries. A device presenting more than EC_MAXFMMU configuration blocks can force writes beyond the array boundary, corrupting adjacent memory structures and potentially disrupting subsequent operations."}], "lastModified": "2026-10-26T15:16:44.540", "sourceIdentifier": "a6d3dc9e-0591-4a13-bce7-0f5b31ff6158"}
