A firmware response with\na length field larger than expected overruns the caller buffer and\nreads past the end of the reply allocation.\n\nReplace the dead -ENOMEM check with an active validation that\nreply-\u003elength fits within val_len before the memcpy.","modified":"2026-10-19T14:16:50.081753594Z","published":"2026-10-18T16:17:37Z","upstream":["CVE-2026-98830"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98830"}],"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-108972.json"}}],"schema_version":"1.9.0"}
