CVE-2026-2100 (GCVE-0-2026-2100)
Vulnerability from nvd – Published: 2026-03-26 20:01 – Updated: 2026-07-07 14:39

Title
P11-kit: null dereference via c_derivekey with specific null parameters
Summary
A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey 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, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states.

A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL.
