{"id":"CVE-2022-2097","aliases":["GHSA-3wx7-46ch-7rq2","RUSTSEC-2022-0032"],"url":"https://o3.security/vulnerability/CVE-2022-2097","summary":"AES OCB fails to encrypt some bytes","details":"AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of \"in place\" encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q (Affected 1.1.1-1.1.1p).","published":"2022-07-05T10:30:13.658Z","modified":"2026-10-28T10:25:32.903263391Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"openssl-src","fixedVersion":"111.22.0"},{"ecosystem":"crates.io","name":"openssl-src","fixedVersion":"300.0.9"}],"fix":null,"references":[{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-332410.html"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-398330.html"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-625862.html"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-794697.html"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-879734.html"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-332410.pdf"},{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=919925673d6c9cfed3c1085497f5dfbbed5fc431"},{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=a98f339ddd7e8f487d6e0088d4a9a42324885a93"},{"type":"WEB","url":"https://www.openssl.org/news/secadv/20220705.txt"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/2xxx/CVE-2022-2097.json"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R6CK57NBQFTPUMXAPJURCGXUYT76NQAK/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/V6567JERRHHJW2GNGJGKDRNHR7SNPZK7/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VCMNWKERPBKOEBNL7CLTTX3ZZCZLH7XA/"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-2097"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202210-02"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20220715-0011/"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20230420-0008/"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20240621-0006/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2023/dsa-5343"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2023/02/msg00019.html"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20240621-0006"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230420-0008"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20220715-0011"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2022-0032.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/VCMNWKERPBKOEBNL7CLTTX3ZZCZLH7XA"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/V6567JERRHHJW2GNGJGKDRNHR7SNPZK7"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/R6CK57NBQFTPUMXAPJURCGXUYT76NQAK"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VCMNWKERPBKOEBNL7CLTTX3ZZCZLH7XA"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/V6567JERRHHJW2GNGJGKDRNHR7SNPZK7"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R6CK57NBQFTPUMXAPJURCGXUYT76NQAK"},{"type":"PACKAGE","url":"https://github.com/alexcrichton/openssl-src-rs"},{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=a98f339ddd7e8f487d6e0088d4a9a42324885a93"},{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=919925673d6c9cfed3c1085497f5dfbbed5fc431"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T10:25:32.903263391Z"}}
