{"cve":"CVE-2026-80745","nvd":{"published":"2026-09-03T13:06:14.007","modified":"2026-09-04T05:17:14.570","status":"Received","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).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.4},"cwes":[],"references":["https://git.kernel.org/stable/c/66694b5f90f3876fccb87bbd02b453cdc33b3ae4","https://git.kernel.org/stable/c/92a9594053831bf4c5886519688e155912befaee"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-80745","score":0.0018,"percentile":0.07539,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
