CVE-2024-9157: 
vulnerability analysis and mitigation

A privilege escalation vulnerability has been identified in CxUIUSvc64.exe and CxUIUSvc32.exe of Synaptics audio drivers (CVE-2024-9157). The vulnerability allows a local authorized attacker to load a DLL in a privileged process. The affected software is considered End-of-Life and should be removed from systems (NVD).

The vulnerability has been assigned a CVSS v3.1 Base Score of 7.8 (HIGH) with the following vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. The vulnerability is classified under CWE-284 (Improper Access Control). The issue specifically affects the Synaptics audio driver service binaries, allowing DLL loading in a privileged context (NVD).

If successfully exploited, this vulnerability could allow an authenticated local attacker to achieve privilege escalation through DLL loading in a privileged process, potentially leading to complete system compromise (NVD, ZDI).

Since the affected software is End-of-Life, the recommended mitigation is to completely remove the Synaptics audio drivers from affected systems. No patches will be provided as the product has reached end-of-support (NVD).
