CVE-2026-12860

A flaw was found in Bouncy Castle for Java. During the RSA PKCS1 verification process, the last two hash bytes are incorrectly skipped when a NULL-omitted path is utilized. This vulnerability could allow an attacker to bypass cryptographic signature verification, potentially leading to the...
