Exploiting this issue also requires a user or application\nto process a maliciously crafted PKCS#12 file. It is uncommon to accept\nuntrusted PKCS#12 files in applications as they are usually used to store\nprivate keys which are trusted by definition. For these reasons, the issue\nwas assessed as Low severity.\n\nThe FIPS modules in 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,\nas the PKCS12 implementation is outside the OpenSSL FIPS module boundary.\n\nOpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this issue.\n\nOpenSSL 1.0.2 is not affected by this issue."},{"lang":"es","value":"Resumen del problema: Puede producirse una desreferencia de puntero inválido o NULL en una aplicación que procesa un archivo PKCS#12 malformado.\n\nResumen del impacto: Una aplicación que procesa un archivo PKCS#12 malformado puede ser inducida a desreferenciar un puntero inválido o NULL en una lectura de memoria, resultando en una denegación de servicio.\n\nExiste una vulnerabilidad de confusión de tipos en el código de análisis de PKCS#12 donde se accede a un miembro de la unión ASN1_TYPE sin validar primero el tipo, causando una lectura de puntero inválido.\n\nLa ubicación está restringida a un espacio de direcciones de 1 byte, lo que significa que cualquier intento de manipulación de puntero solo puede apuntar a direcciones entre 0x00 y 0xFF. Este rango corresponde a la página cero, que no está mapeada en la mayoría de los sistemas operativos modernos y resultará de forma fiable en un fallo, lo que lleva solo a una denegación de servicio. Para explotar este problema también es preciso que un usuario o aplicación procese un archivo PKCS#12 creado maliciosamente. Es poco común aceptar archivos PKCS#12 no confiables en aplicaciones, ya que generalmente se utilizan para almacenar claves privadas que son confiables por definición. Por estas razones, el problema fue evaluado como de baja severidad.\n\nLos módulos FIPS en 3.5, 3.4, 3.3 y 3.0 no se ven afectados por este problema, ya que la implementación de PKCS12 está fuera del límite del módulo FIPS de OpenSSL.\n\nOpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 y 1.1.1 son vulnerables a este problema.\n\nOpenSSL 1.0.2 no se ve afectado por este problema."}],"affected":[{"source":"openssl-security@openssl.org","affectedData":[{"vendor":"OpenSSL","product":"OpenSSL","defaultStatus":"unaffected","versions":[{"version":"3.6.0","lessThan":"3.6.1","versionType":"semver","status":"affected"},{"version":"3.5.0","lessThan":"3.5.5","versionType":"semver","status":"affected"},{"version":"3.4.0","lessThan":"3.4.4","versionType":"semver","status":"affected"},{"version":"3.3.0","lessThan":"3.3.6","versionType":"semver","status":"affected"},{"version":"3.0.0","lessThan":"3.0.19","versionType":"semver","status":"affected"},{"version":"1.1.1","lessThan":"1.1.1ze","versionType":"custom","status":"affected"}]}]},{"source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","affectedData":[{"vendor":"Siemens","product":"SIMATIC S7-1500 TM MFP - GNU/Linux subsystem","defaultStatus":"unknown","versions":[{"version":"0","lessThan":"*","versionType":"custom","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-01-28T20:03:18.604129Z","id":"CVE-2026-22795","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"openssl-security@openssl.org","type":"Secondary","description":[{"lang":"en","value":"CWE-754"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"1.1.1","versionEndExcluding":"1.1.1ze","matchCriteriaId":"E000B986-6A31-468F-9EA3-B9D16DB16FB2"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0.0","versionEndExcluding":"3.0.19","matchCriteriaId":"C76C5F55-5243-4461-82F5-2FEBFF4D59FA"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.3.0","versionEndExcluding":"3.3.6","matchCriteriaId":"F5292E9E-6B50-409F-9219-7B0A04047AD8"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4.0","versionEndExcluding":"3.4.4","matchCriteriaId":"B9D3DCAE-317D-4DFB-93F0-7A235A229619"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.5.0","versionEndExcluding":"3.5.5","matchCriteriaId":"1CAC7CBE-EC03-4089-938A-0CEEB2E09B62"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.6.0","versionEndExcluding":"3.6.1","matchCriteriaId":"68352537-5E99-4F4D-B78A-BCF0353A70A5"}]}]}],"references":[{"url":"https://github.com/openssl/openssl/commit/2502e7b7d4c0cf4f972a881641fe09edc67aeec4","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://github.com/openssl/openssl/commit/572844beca95068394c916626a6d3a490f831a49","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://github.com/openssl/openssl/commit/7bbca05be55b129651d9df4bdb92becc45002c12","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://github.com/openssl/openssl/commit/eeee3cbd4d682095ed431052f00403004596373e","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://github.com/openssl/openssl/commit/ef2fb66ec571564d64d1c74a12e388a2a54d05d2","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://openssl-library.org/news/secadv/20260127.txt","source":"openssl-security@openssl.org","tags":["Vendor Advisory"]},{"url":"https://cert-portal.siemens.com/productcert/html/ssa-265688.html","source":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e"}]}}]}
