The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:49667 advisory.

    The p11-kit packages provide a mechanism to manage PKCS#11 modules. The p11-kit-trust subpackage includes     a PKCS#11 trust module that provides certificate anchors and black lists based on configuration files.

    Security Fix(es):

    * p11-kit: Stack exhaustion via unbounded recursion in RPC attribute parsing (CVE-2026-13757)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2026-13757)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of p11-kit installed on the remote host is prior to 0.26.4. It is, therefore, affected by a vulnerability as referenced in the SSA:2026-191-01 advisory.

    New p11-kit packages are available for Slackware 15.0 and -current to fix a security issue.
