Linux Distros Unpatched Vulnerability : CVE-2026-83598

high Nessus Plugin ID 349160

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.

- Netdata is an open source observability tool. From rom 2.0.0 until 2.10.4, during Netdata Windows Agent MSI repair, powershell.exe runs as SYSTEM without -NoProfile and loads %USERPROFILE%\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 from the low-privileged user who initiated repair. Commands placed in that profile before repair therefore execute with SYSTEM privileges. This vulnerability is fixed in 2.10.4. (CVE-2026-83598)

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

Solution

There is no known solution at this time.
