Inside the loop, the\ncondition to skip processing extra bytes is:\n\n    if (i > mxt_obj_size(object))\n        continue;\n\nSince i is a 0-based index, the valid indices for the object are 0 through\nmxt_obj_size(object) - 1.\n\nWhen i == mxt_obj_size(object), the condition evaluates to false, and the\ncode processes the byte instead of discarding it.\n\nThis causes the code to calculate byte_offset = reg + i - cfg->start_ofs\nand writes the byte there, overwriting exactly one byte of the adjacent\ninstance or object.\n\nUpdate the boundary check to skip extra bytes correctly by using >=.","published":"2026-07-19T16:17:09.000Z","lastModified":"2026-07-27T17:44:24.000Z","status":"Awaiting Analysis","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00211,"percentile":0.11196,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
