If this is done with an SSL object\\nimplementing the QUIC protocol, NULL pointer dereference will happen if\\nthe examined cipher ID is unknown or unsupported.\\n\\nAs it is not very common to call this function in applications using the QUIC \\nprotocol and the worst outcome is Denial of Service, the issue was assessed\\nas Low severity.\\n\\nThe vulnerable code was introduced in the 3.2 version with the addition\\nof the QUIC protocol support.\\n\\nThe FIPS modules in 3.6, 3.5, 3.4 and 3.3 are not affected by this issue,\\nas the QUIC implementation is outside the OpenSSL FIPS module boundary.\\n\\nOpenSSL 3.6, 3.5, 3.4 and 3.3 are vulnerable to this issue.\\n\\nOpenSSL 3.0, 1.1.1 and 1.0.2 are not affected by this issue.”,”published”:”2026-01-27T16:01:20.824Z”,”modified”:”2026-01-29T14:53:03.572Z”,”type”:”cve”,”title”:”NULL dereference in SSL_CIPHER_find() function on unknown cipher ID”,”source”:”openssl”,”references”:”https:\/\/openssl-library.org\/news\/secadv\/20260127.txt\\nhttps:\/\/github.com\/openssl\/openssl\/commit\/b2539639400288a4580fe2d76247541b976bade4\\nhttps:\/\/github.com\/openssl\/openssl\/commit\/1f08e54bad32843044fe8a675948d65e3b4ece65\\nhttps:\/\/github.com\/openssl\/openssl\/commit\/7c88376731c589ee5b36116c5a6e32d5ae5f7ae2\\nhttps:\/\/github.com\/openssl\/openssl\/commit\/d75b309879631d45b972396ce4e5102559c64ac7″,”id”:”CVE-2025-15468″,”bulletinFamily”:””,”cwe”:[“CWE-476″],”cvelist”:null,”sourceData”:”OpenSSL OpenSSL 3.6.0\\nOpenSSL OpenSSL 3.5.0\\nOpenSSL OpenSSL 3.4.0\\nOpenSSL OpenSSL 3.3.0″,”sourceHref”:””,”cvss”:{“score”:5.9,”severity”:”MEDIUM”,”vector”:”CVSS:3.1\/AV:N\/AC:H\/PR:N\/UI:N\/S:U\/C:N\/I:N\/A:H”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”OpenSSL”,”version”:”3.6.0″,”vendor”:”OpenSSL”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
