{"id":"CVE-2026-32281","summary":"Inefficient policy validation in crypto/x509","details":"Validating certificate chains which use policies is unexpectedly inefficient when certificates in the chain contain a very large number of policy mappings, possibly causing denial of service. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.","aliases":["BIT-golang-2026-32281","GO-2026-4946"],"modified":"2026-05-15T04:14:36.703601374Z","published":"2026-04-08T01:06:58.354Z","related":["CGA-mhq6-cw97-rcc6","SUSE-SU-2026:1320-1","SUSE-SU-2026:1321-1","SUSE-SU-2026:1580-1","SUSE-SU-2026:1581-1","SUSE-SU-2026:21355-1","SUSE-SU-2026:21356-1","openSUSE-SU-2026:10514-1","openSUSE-SU-2026:10525-1","openSUSE-SU-2026:20570-1","openSUSE-SU-2026:20571-1"],"database_specific":{"cna_assigner":"Go","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"1.25.9"},{"introduced":"1.26.0-0"},{"fixed":"1.26.2"}]}],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32281.json"},"references":[{"type":"WEB","url":"https://go.dev/cl/758061"},{"type":"WEB","url":"https://go.dev/issue/78281"},{"type":"WEB","url":"https://groups.google.com/g/golang-announce/c/0uYbvbPZRWU"},{"type":"WEB","url":"https://pkg.go.dev"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2026-4946"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32281.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32281"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
