CVE-2026-2100 PUBLISHED CVSS 5.300000190734863 MEDIUM

A flaw was found in p11-kit.

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.
