PHP Heap-based Buffer Overflow Vulnerability - CVE-2026-14355

In PHP versions 8.2. before 8.2.32 8.3. before 8.3.32 8.4. before 8.4.23 8.5. before 8.5.8 the AES-WRAP-PAD algorithm implementation in OpenSSL extension contains a buffer allocation flaw. The output buffer for the AES key-wrap-with-padding operation is sized from the plaintext length without accounting for RFC 5649 expansion. This may cause OpenSSL to write beyond allocated memory corrupting heap metadata and triggering application abort.
