If the\nfirmware file is shorter than 8 bytes, fw_size - 8 underflows and the\naccess reads out of bounds. Validate the firmware size before indexing.","modified":"2026-09-18T05:37:08Z","published":"2026-09-16T11:16:56Z","upstream":["CVE-2026-89878"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89878"}],"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-101256.json"}}],"schema_version":"1.9.0"}
