CVE-2026-22166: UAF Crash in GPU DDK 1.18.0–26.1
Plattform

Komponente

CVE-2026-22166 describes a use-after-free (UAF) crash vulnerability affecting the GPU DDK component. This flaw arises when a web page containing unusual WebGPU content is loaded into the GPU GLES render process, leading to a crash in the GPU GLES user-space shared library. Successful exploitation, particularly on platforms where the graphics workload process has system privileges, could potentially enable subsequent exploits on the system, compromising system integrity. The vulnerability impacts versions 1.18.0–26.1 RTM.
Auswirkungen und Angriffsszenarien
The primary impact of CVE-2026-22166 lies in its potential to escalate privileges and enable arbitrary code execution. An attacker could craft malicious WebGPU content designed to trigger the UAF crash. If the process handling this content has elevated system privileges, the crash could be leveraged to overwrite memory, potentially allowing the attacker to inject and execute arbitrary code. This could lead to complete system compromise, including data theft, malware installation, and denial of service. The blast radius extends to any system running the affected GPU DDK versions with vulnerable configurations.
Ausnutzungskontext
The exploitation context for CVE-2026-22166 is currently unclear. It is not listed on KEV (Kernel Exploit Vulnerability) or EPSS (Exploit Prediction Scoring System). Public proof-of-concept (POC) code is not yet available. Given the potential for privilege escalation, it's prudent to monitor for emerging exploitation attempts. The vulnerability was published on 2026-05-01.

Mitigation und Workarounds
The immediate mitigation for CVE-2026-22166 is to upgrade to a patched version of the GPU DDK. Unfortunately, a specific fixed version is not provided in the CVE data. Until a patch is available, consider implementing stricter input validation for WebGPU content to prevent the loading of unusual or potentially malicious content. Web application firewalls (WAFs) configured to inspect and filter WebGPU requests could provide an additional layer of defense. Monitor system logs for crash reports related to the GPU GLES user-space shared library. After upgrading, confirm the fix by attempting to load the previously triggering WebGPU content and verifying that the crash no longer occurs.
