Description

This security bulletin contains information about 1 vulnerability.


1) Uncontrolled Recursion (CVE-ID: CVE-2026-13757)

CWE-ID: CWE-674 - Uncontrolled Recursion

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled recursion in the p11_rpc_message_get_attribute and p11_rpc_message_get_attribute_array_value functions when processing nested template attributes. A remote attacker can send a specially crafted request with deeply nested attributes via the RPC Unix domain socket to cause a denial of service.

Exploitation can lead to stack exhaustion and crash the server process.
