Linux Distros Unpatched Vulnerability : CVE-2026-19617

high Nessus Plugin ID 335358

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

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 libdm. A local attacker could craft a malicious Logical Volume Manager (LVM) metadata configuration with deeply nested structures. This could lead to uncontrolled recursion in the libdm configuration file parser, exhausting the stack and causing any LVM command reading the metadata to crash.
This vulnerability results in a Denial of Service (DoS) for affected systems. (CVE-2026-19617)

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

Solution

There is no known solution at this time.
