Linux Distros Unpatched Vulnerability : CVE-2026-111555

medium Nessus Plugin ID 366468

Language:

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 luksmeta. Improper boundary validation of metadata slots allows an attacker capable of supplying or modifying a disk header to redirect wipe or load operations outside the intended metadata area. An attacker could exploit this vulnerability by providing a crafted header with valid checksums to overwrite or zero out encrypted payload data, resulting in persistent data loss and corrupted storage.
 Exploitation typically requires privileged access to modify raw block devices or the ability to induce an administrator to process an untrusted disk image. (CVE-2026-111555)

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

Solution

There is no known solution at this time.
