{"id":"AZL-102891","summary":"CVE-2026-90245 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfbdev: kyro: Validate overlay viewport coordinates\n\nThe overlay viewport end coordinates are computed from the viewport\norigin and dimensions using 32-bit unsigned arithmetic. 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.","modified":"2026-09-18T14:16:35.920623433Z","published":"2026-09-17T17:17:20Z","upstream":["CVE-2026-90245"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90245"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102891.json"}}],"schema_version":"1.9.0"}
