CVE-2026-22795

CVE-2026-22795 affects OpenSSL PKCS#12 parsing: a type confusion in the PKCS#12 processor and an ASN1_TYPE validation gap can allow a crafted PKCS#12 file to trigger an invalid/NULL pointer dereference, causing Denial of Service. Affected releases include OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0, and 1.1....

CVE-2026-22795

Issue summary: An invalid or NULL pointer dereference can happen in an application processing a malformed PKCS12 file. Impact summary: An application processing a malformed PKCS12 file can be caused to dereference an invalid or NULL pointer on memory read, resulting in a Denial of Service. A type...

CVE-2025-69421 NULL Pointer Dereference in PKCS12_item_decrypt_d2i_ex function

Issue summary: Processing a malformed PKCS12 file can trigger a NULL pointer dereference in the PKCS12itemdecryptd2iex function. Impact summary: A NULL pointer dereference can trigger a crash which leads to Denial of Service for an application processing PKCS12 files. The PKCS12itemdecryptd2iex...

CVE-2025-69421

CVE-2025-69421 is a vulnerability in OpenSSL where a NULL pointer dereference in the PKCS12_item_decrypt_d2i_ex() function can crash applications that process malformed PKCS#12 files, causing Denial of Service. The issue arises because oct is not checked for NULL before dereferencing it when PKCS...

CVE-2025-69419

Issue summary: Calling PKCS12getfriendlyname function on a maliciously crafted PKCS12 file with a BMPString UTF-16BE friendly name containing non-ASCII BMP code point can trigger a one byte write before the allocated buffer. Impact summary: The out-of-bounds write can cause a memory corruption...

CVE-2025-11187 Improper validation of PBMAC1 parameters in PKCS#12 MAC verification

Issue summary: PBMAC1 parameters in PKCS12 files are missing validation which can trigger a stack-based buffer overflow, invalid pointer or NULL pointer dereference during MAC verification. Impact summary: The stack buffer overflow or NULL pointer dereference may cause a crash leading to Denial o...

CVE-2025-69421

A flaw was found in OpenSSL. This vulnerability allows a remote attacker to trigger a Denial of Service DoS by providing a specially crafted, malformed PKCS12 file to an application that processes it. The flaw occurs due to a NULL pointer dereference in the PKCS12itemdecryptd2iex function when...

CVE-2025-11187

A flaw was found in OpenSSL. When an application processes a maliciously crafted PKCS12 file, an attacker can exploit a stack buffer overflow or a NULL pointer dereference. This can lead to a denial of service DoS by crashing the application, and in some cases, may enable arbitrary code execution...
