A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.","severity":{"version":"3.1","score":3.7,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","level":"low","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00804,"percentile":0.57009,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-179"],"published":"2026-04-30T17:41:28Z","modified":"2026-10-29T11:42:23Z","fixes":[{"ecosystem":"Alpine:v3.20","package":"gnutls","fixed_in":["3.8.13-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.21","package":"gnutls","fixed_in":["3.8.13-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.22","package":"gnutls","fixed_in":["3.8.13-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"gnutls","fixed_in":["3.8.13-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"gnutls","fixed_in":["3.8.13-r0"],"sources":["osv"]},{"ecosystem":"Azure
