AI-suggested
Red Hat has released fixed packages for p11-kit version 0.26.4-1.hum1 that address CVE-2026-13757. Users should apply these updates to remediate the vulnerability. Patch status is confirmed by Red Hat advisories RHSA-2026:37469 and RHSA-2026:38342. No other mitigation or workaround is indicated.
Description
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.
