What is CVE-2024-52336?
CVE-2024-52336 is a high-severity vulnerability in Red Hat Fast Datapath for RHEL 7, published on 26 Nov 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
A script injection vulnerability was identified in the Tuned package. The `instance_create()` D-Bus function can be called by locally logged-in users without authentication. This flaw allows a local non-privileged user to execute a D-Bus call with `script_pre` or `script_post` options that permit arbitrary scripts with their absolute paths to be passed. These user or attacker-controlled executable scripts or programs could then be executed by Tuned with root privileges that could allow attackers to local privilege escalation.
