Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-d314ce6051 advisory.

 This update adds a new module, `mod_procfs`, which is enabled by default. It addressses CVE-2026-35025 (ACL bypass via `/proc/self/root` path prefix), by disallowing any file accesses via `procfs` filesystems.
