CVE-2026-22795
Description
Issue summary: An invalid or null pointer dereference can happen inan application processing a malformed PKCS#12 file.Impact summary: An application processing a malformed PKCS#12 file can becaused to dereference an invalid or null pointer on memory read, resultingin a Denial of Service.A type confusion vulnerability exists in PKCS#12 parsing code wherean ASN1_TYPE union member is accessed without first validating the type,causing an invalid pointer read.The location is constrained to a 1-byte address space, meaning anyattempted pointer manipulation can only target addresses between 0x00 and 0xFF.This range corresponds to the zero page, which is unmapped on most modernoperating systems and will reliably result in a crash, leading only to aDenial of Service. Exploiting this issue also requires a user or applicationto process a maliciously crafted PKCS#12 file. It is uncommon to acceptuntrusted PKCS#12 files in applications as they are usually used to storeprivate keys which are trusted by definition. For these reasons, the issuewas assessed as Low severity.The FIPS modules in 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,as the PKCS12 implementation is outside the OpenSSL FIPS module boundary.OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this issue.OpenSSL 1.0.2 is not affected by this issue.
