This update for openssl-11 fixes the following issues: CVE-2026-28387: Potential use-after-free in DANE client code bsc1260441. CVE-2026-28388: NULL Pointer Dereference When Processing a Delta CRL bsc1260442. CVE-2026-28389: Possible NULL dereference when processing CMS KeyAgreeRecipientInfo...

nodejs: Nodejs memory leak

A resource consumption flaw has been discovered in NodeJS. A memory leak in Node.js’s OpenSSL integration occurs when converting X.509 certificate fields to UTF-8 without freeing the allocated buffer. When applications call socket.getPeerCertificatetrue, each certificate field leaks memory,...

CVE-2026-28386

A flaw was found in openssl. Applications using AES-CFB128 encryption or decryption on systems with AVX-512 and VAES support may experience a Denial of Service DoS. This occurs when processing partial cipher blocks, specifically if the input buffer ends at a memory page boundary and the subsequen...

CVE-2026-28389

A flaw was found in OpenSSL. A remote attacker could exploit this by sending a specially crafted Cryptographic Message Syntax CMS EnvelopedData message with KeyAgreeRecipientInfo. This vulnerability arises because the software attempts to process an optional field without verifying its existence,...

CVE-2026-28388

A flaw was found in OpenSSL. When processing a malformed delta Certificate Revocation List CRL that lacks a required CRL Number extension, a NULL pointer dereference can occur. This vulnerability can be exploited by a remote attacker who provides a specially crafted delta CRL to an application th...

CVE-2026-28387

A flaw was found in OpenSSL. An uncommon configuration of clients performing DANE TLSA-based server authentication, when paired with uncommon server DANE TLSA records, may result in a use-after-free and/or double-free on the client side. This vulnerability could lead to data corruption, applicati...

CVE-2026-5501

CVE-2026-5501 involves wolfSSL’s X509_verify_cert in the OpenSSL compatibility layer. The vulnerability arises when a certificate chain is presented where the leaf’s signature is not checked if an untrusted intermediate (CA:FALSE) signed by a trusted root is supplied. An attacker with any leaf ce...
