A crafted offset like 0xFFFFFFF0 becomes -16, placing hdr 16 bytes\nbefore the table buffer.  The subsequent avail check was bypassed\nbecause the negative int was promoted to a large size_t in the\nexpression \"table_sz - offset - sizeof(*hdr)\", yielding a large positive\navail and letting the out-of-bounds hdr-\u003etype read proceed undetected.\n\nStore the offset as u32 and validate it with unsigned comparisons before\nany pointer arithmetic.","modified":"2026-09-18T14:15:26.715211249Z","published":"2026-09-17T17:17:29Z","upstream":["CVE-2026-90314"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90314"}],"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-102039.json"}}],"schema_version":"1.9.0"}
