CVE-2026-12816

Bouncy Castle for Java contains an IESEngine stream-mode MAC forgery flaw via a length-dependent KDF split, affecting versions before 1.85 (and Bouncy Castle for Java LTS before 2.73.12). The issue is documented in CVE-2026-12816 with no exploitation details provided in the supplied sources. No r...

openssl: OpenSSL: Denial of Service due to heap out-of-bounds read in CMS password-based decryption

A flaw was found in OpenSSL. When processing attacker-supplied Cryptographic Message Syntax CMS data using password-based decryption, an attacker can choose a stream-mode Key Encryption Key KEK cipher. This can trigger a heap out-of-bounds read, potentially causing an application crash and leadin...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in kekunwrapkey in the CMS component. An attacker supplying malicious CMS data can select a stream-mode KEK cipher via the OID in the PWRI keyEncryptionAlgorithm, defeating the block-length minimum-length guard so tha...

EUVD-2026-35475

Issue summary: When CMS password-based decryption RFC 3211 / PWRI key unwrap processes attacker-supplied CMS data, an attacker-chosen stream-mode KEK cipher can trigger a heap out-of-bounds read in kekunwrapkey. Impact summary: A heap buffer over-read may trigger a crash which leads to Denial of...
