OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.

Security Fix(es):

• openssl: OpenSSL: Denial of Service via unbounded memory growth in QUIC server (CVE-2026-14456)
• openssl: QUIC server may trigger double free when processing INITIAL packet (CVE-2026-18798)
• openssl: heap buffer overflow in CMS key unwrapping (CVE-2026-63072)
• openssl: invalid pointer dereference in CMP server via crafted protectionAlg (CVE-2026-63076)

• openssl: untrusted sender DN used as format string in CMP response validation (CVE-2026-63073)
• openssl: CMP indefinite cache growth of ExtraCerts (CVE-2026-63074)
• openssl: QUIC ACK-only packet retention can cause memory exhaustion (CVE-2026-63075)

Bug Fix(es) and Enhancement(s):

• openssl: HollowByte remote memory-exhaustion DoS fix may be missing [AlmaLinux 10.2.z] (JIRA:AlmaLinux-212362)
