Its\narp_dev field may contain IFNAMSIZ bytes without a NUL terminator.\n\nSuch input is passed to dev_get_by_name_rcu() or __dev_get_by_name(), where\nstrcmp() can read past the end of the stack object when a matching\nalternative interface name exists.\n\nTerminate the field before the lookup to prevent the out-of-bounds read.","modified":"2026-10-19T14:16:32.029354700Z","published":"2026-10-18T16:17:00Z","upstream":["CVE-2026-98495"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98495"}],"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-109392.json"}}],"schema_version":"1.9.0"}
