Large input\nvalues can cause these calculations to wrap around before the resulting\ncoordinates are passed to SetOverlayViewPort().\n\nSetOverlayViewPort() packs the viewport coordinates into 16-bit\nregister fields. The X coordinates are additionally adjusted by +2\nand +1 before being written. Validate the coordinate calculations\nfor 32-bit wraparound and ensure that the adjusted coordinates fit\nwithin their 16-bit register fields before calling\nSetOverlayViewPort().\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2ac6e30a552e6f9932c21c865a5c69f40c8aef64","https://git.kernel.org/stable/c/33e54e3e0b2ca959304e62c3d84f0ad49bbe1afe","https://git.kernel.org/stable/c/413d763439ba68e5d547538e6b6c7de97d5818a5","https://git.kernel.org/stable/c/7b5c7bc55e13e7f5ac7b1eaf5c6d690389ea5ee3","https://git.kernel.org/stable/c/7bf36dc23bcf3496dec274a46ae0aaff4961ea03"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90245","score":0.00211,"percentile":0.11182,"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).
