DescriptionNVD

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.

AnalysisAI

p11-kit remote token handling fails to validate NULL derive mechanism parameters in C_DeriveKey operations, allowing unauthenticated remote attackers to trigger NULL pointer dereferences and undefined memory access in the RPC client layer. This denial-of-service vulnerability affects Red Hat Enterprise Linux versions 6 through 10 and OpenShift Container Platform 4, with a CVSS score of 5.3 reflecting moderate availability impact. …
