Horizon Alert
Summary of the vulnerability and why it matters
Certain Qualcomm chipsets contain a vulnerability in how they handle address deregistration during error conditions. This can lead to failures when allocating new GPU addresses. This issue affects various Snapdragon chipsets used in mobile, IoT, and computing devices.
- Vulnerable Qualcomm chipsets
- Failure in GPU address allocation
- Potential system instability or denial of service
Attack Path
How an attacker could exploit the issue
This vulnerability allows for a denial-of-service condition due to improper handling of GPU address allocation failures. An attacker with local access could exploit this by triggering an error during address deregistration, which prevents new GPU addresses from being allocated. This ultimately impacts the availability of the system's graphical processing capabilities.
- Local access required.
- Trigger error during address deregistration.
- GPU address allocation failure occurs.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability affects Qualcomm chipsets in various Snapdragon products. Exploitation could lead to GPU address allocation failures, potentially causing system instability or denial of service. The vulnerability requires local access and is classified as internal, indicating it is not directly exposed to the public internet.
- Likely attacker skill level: Low
- Required access or conditions: Local access required
- Business risk or urgency: Low
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability has been identified within Qualcomm chipsets, affecting various Snapdragon products. The improper handling of address deregistration on failure can lead to a new GPU address allocation failure. As this vulnerability is classified as internal and requires local access to exploit, the primary risk is to individual devices rather than widespread organizational systems.
- Identify devices with affected chipsets.
- Limit local access to devices.
- Apply vendor updates and verify.
