A malformed firmware image without a\nNUL terminator can therefore make the parser walk past the end of the\nfirmware buffer before the later size checks run.\n\nAdd a small bounded string-length helper and use it for all description\nfields that are parsed from the firmware buffer. Keep the existing size\nchecks for the fixed bytes that follow each string.","state":0,"publishedAt":"2026-08-10T12:03:25.193+00:00","modifiedAt":"2026-10-19T21:09:05.718+00:00","affected":[{"ecosystem":"Vendor
