The\nsubsequent division result overflows the u32 in variable, truncating\nto a pseudo-random positive value. When this is passed to\nltc4282_write_voltage_byte(), it is clamped to the maximum limit instead\nof zero.\n\nClamp val to 0 and to the maximum supported upper limit before the cast\nand assign the result to a 64-bit temporary variable before the division\nto avoid the underflow and an also possible overflow.","published":"2026-08-22T16:16:43.000Z","lastModified":"2026-10-14T13:10:00.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00209,"percentile":0.1094,"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.
