The footer offset\nand region count come from flash contents and are not checked against the\nerase block or the local image-info array before use.\n\nReject v2 entries whose image information offset would underflow the\nerase block calculation, and reject region counts that cannot fit in the\nlocal image-info array before walking region entries.","modified":"2026-09-17T14:15:52.883387499Z","published":"2026-09-16T11:17:05Z","upstream":["CVE-2026-89954"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89954"}],"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-101358.json"}}],"schema_version":"1.9.0"}
