Additionally, most of its usage in DPMS sequences\nis for stream-\u003esink-\u003elink, which can be replaced with stream-\u003elink,\nas the two should always be the same.\n\n[How]\n* Replace stream-\u003esink-\u003elink in DPMS on/off\n* Add assert to USB4 BW allocation where sink is required\n* Avoid inconsistencies in resource access, e.g. don't repeat\nstream-\u003elink after it was already saved to a local variable\n* Pull out effective VPG calculation to helper getter\n* Formatting fixes","modified":"2026-10-30T05:35:37Z","published":"2026-10-23T13:17:13Z","upstream":["CVE-2026-98926"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98926"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-110705.json"}}],"schema_version":"1.9.2"}
