If the PPM\nreturns an invalid GET_CURRENT_CAM response above UCSI_MAX_ALTMODES and\nnot equal to 0xff, the kernel may crash with an array index OOB error.\n\nUpdate the UCSI displayport driver to verify the current cam is less\nthan UCSI_MAX_ALTMODES before accessing the port altmode array.","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:N/A:H","score":7.7},"cwes":[],"references":["https://git.kernel.org/stable/c/04cec690b1fd9d1c4c314b91a10d8c68a3acfe18","https://git.kernel.org/stable/c/1ffed96ef986e2cdf986aa4a4506a5e6dcdf4456","https://git.kernel.org/stable/c/33a81acd2d1d0667d4eff93cb90339fa53e617e8","https://git.kernel.org/stable/c/58e0ee293ec5e06cacbe3953ad44042f1473dae9","https://git.kernel.org/stable/c/83f1abd62cc134700ba92e1e2dc650a49a185497"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-90025","score":0.00172,"percentile":0.0658,"date":"2026-10-25"},"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).
