A zero-length TEXT entry passes\nvalidation but causes an underflow in the null-termination logic:\n\n  property-\u003evalue.text[property-\u003elength * 4 - 1] = '\\0';\n\nWhen property-\u003elength is 0 this writes to offset -1 relative to\nthe allocation.\n\nReject zero-length entries early in the validator since they have no\nvalid representation in the XDomain property protocol.","modified":"2026-08-28T17:45:57.257321379Z","published":"2026-06-25T09:16:32Z","upstream":["CVE-2026-53150"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53150"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.143.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-90615.json"}}],"schema_version":"1.9.0"}
