{"id":"CVE-2026-80745","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-80745","generatedAt":"2026-10-28T00:08:01.072Z","title":"In the Linux kernel, the following vulnerability has been resolved: regulator: fp9931: Fix VPOS/VNEG voltage selector table The VPOSNEG_table[] mapping does not match the FP9931 datasheet.","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nregulator: fp9931: Fix VPOS/VNEG voltage selector table\n\nThe VPOSNEG_table[] mapping does not match the FP9931 datasheet.\n\nThe datasheet defines the VPOS/VNEG voltage mapping as:\n\n  00h-04h ->  7.04V (-7.04V)\n  05h     ->  7.26V (-7.26V)\n  06h     ->  7.49V (-7.49V)\n  ...\n  28h-3Fh -> 15.06V (-15.06V)\n\nHowever, VPOSNEG_table[] has two issues:\n\n1. Selector 0x00~0x04 should all map to 7.04V (5 entries), but the\n   table has 6 entries of 7.04V, causing all subsequent entries to be\n   shifted by one position.\n\n2. Selectors 0x29~0x3F should all clamp to 15.06V (23 entries), but\n   the table has only 41 entries. Any selector value above 0x28\n   would result in an out-of-bounds table access.\n\nFix both issues by removing the duplicate 7.04V entry and appending\nthe missing 23 clamped 15.06V entries, bringing the table to the\ncorrect size of 64 entries (0x00~0x3F).","published":"2026-09-03T13:06:14.000Z","lastModified":"2026-09-04T05:17:15.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.0018,"percentile":0.07474,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.18%).
