Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2026-4105. PoCs published by exploitintel.
AI-analyzed exploit summary This repository contains functional exploit code for CVE-2026-4105, a local privilege escalation vulnerability in systemd-machined (v225–v259.3) due to improper machine class access control. The PoC includes multiple vectors (D-Bus, Varlink) and a bypass for the patched version (v259.4).
Description
A flaw was found in systemd. The systemd-machined service contains an Improper Access Control vulnerability due to insufficient validation of the class parameter in the RegisterMachine D-Bus (Desktop Bus) method. A local unprivileged user can exploit this by attempting to register a machine with a specific class value, which may leave behind a usable, attacker-controlled machine object. This allows the attacker to invoke methods on the privileged object, leading to the execution of arbitrary commands with root privileges on the host system.
