Any driver that selects a non-VR11 VID mode\nand exposes a regulator (or hwmon vout setter) sent dangerously\nwrong codes to PMBUS_VOUT_COMMAND -- e.g. an nvidia195mv part asked\nfor 200 mV got the VR11 clamp to 500 mV encoded as 0xB2, which the\nchip interprets as 1080 mV.\n\nMirror pmbus_reg2data_vid() so writes round-trip with reads.","published":"2026-08-15T06:22:13.000Z","lastModified":"2026-10-21T13:19:37.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00171,"percentile":0.06435,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%).
