Details
A vulnerability, which was classified as problematic, has been found in Red Hat Enterprise Linux 10, Enterprise Linux 6, Enterprise Linux 7, Enterprise Linux 8, Enterprise Linux 9, Hardened Images and OpenShift Container Platform 4. Affected by this issue is the function p11_rpc_message_get_attribute of the component p11-kit. The manipulation of the argument CKA_WRAP_TEMPLATE/CKA_UNWRAP_TEMPLATE/CKA_DERIVE_TEMPLATE with an unknown input leads to a recursion vulnerability. Using CWE to declare the problem leads to CWE-674. The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. Impacted is availability. CVE summarizes:
A flaw was found in p11-kit. The RPC message attribute parsing functions p11_rpc_message_get_attribute() and p11_rpc_message_get_attribute_array_value() form a mutually-recursive call chain with no recursion depth limit when processing nested CKA_WRAP_TEMPLATE, CKA_UNWRAP_TEMPLATE, and CKA_DERIVE_TEMPLATE attributes. An unauthenticated attacker with local access to the p11-kit RPC Unix domain socket can send a specially crafted request with deeply nested template attributes, causing stack exhaustion and crashing the p11-kit server process and its dependent services.
The advisory is available at access.redhat.com. This vulnerability is handled as CVE-2026-13757 since 06/29/2026. The exploitation is known to be easy.
