RLSA-2026:18599 Moderate: p11-kit security update

The p11-kit packages provide a mechanism to manage PKCS11 modules. The p11-kit-trust subpackage includes a PKCS11 trust module that provides certificate anchors and black lists based on configuration files. Security Fixes: p11-kit: p11-kit: NULL dereference via CDeriveKey with specific NULL...

p11-kit: NULL dereference via C_DeriveKey with specific NULL parameters

A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the CDeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potential...

Linux Distros Unpatched Vulnerability : CVE-2026-41676

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.27 to before 0.10.78, Deriver::derive and PkeyCtxRef::derive sets len = buf.l...

CVE-2026-41676

A flaw was found in rust-openssl, a library that provides cryptographic functionalities by binding to OpenSSL. When interacting with OpenSSL 1.1.x, the Deriver::derive function does not correctly manage buffer sizes during key derivation operations. This oversight can lead to a memory overflow,...

CVE-2026-41676 rust-openssl: Deriver::derive and PkeyCtxRef::derive can overflow short buffers on OpenSSL 1.1.1

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.27 to before 0.10.78, Deriver::derive and PkeyCtxRef::derive sets len = buf.len and passes it as the in/out length to EVPPKEYderive, relying on OpenSSL to honor it. On OpenSSL 1.1.x, X25519, X448, DH and HKDF-extra...
