Overview
CVE-2025-58410 is a critical vulnerability discovered in certain GPU drivers, allowing a non-privileged user to gain unintended write access to memory buffers that are intended to be read-only. This potentially allows for privilege escalation and other malicious activities.
Technical Details
The vulnerability stems from improper handling of memory protections for buffer resources within the GPU driver. Specifically, software installed and run as a non-privileged user may conduct improper GPU system calls. These calls bypass intended security mechanisms, granting write permissions to memory buffers that are designated as read-only. The root cause is a flaw in how the driver manages the memory protection attributes when these buffers are allocated and accessed.
CVSS Analysis
Currently, a CVSS score is not available (N/A) for CVE-2025-58410. However, given the potential for privilege escalation, it is likely to be rated as High or Critical once a CVSS score is assigned. The lack of a CVSS score at the time of publication doesn’t diminish the importance of addressing the vulnerability.
Possible Impact
The exploitation of CVE-2025-58410 could have severe consequences:
- Privilege Escalation: A non-privileged user could gain elevated privileges, potentially gaining root or administrator access to the system.
- Data Corruption: Malicious code could overwrite critical system data, leading to instability or complete system failure.
- Code Injection: Attackers could inject malicious code into the affected memory regions, leading to arbitrary code execution with elevated privileges.
- Denial of Service (DoS): The vulnerability could be exploited to trigger a denial-of-service condition, rendering the system unusable.
Mitigation or Patch Steps
The primary mitigation strategy is to update the affected GPU drivers to the latest version provided by the vendor. Imagination Technologies has been notified of this issue. Keep an eye on their security advisories and driver updates.
To mitigate the risk before a patch is available, consider limiting access to GPU resources for non-trusted applications. This may involve:
- Monitoring GPU usage for suspicious activity.
- Employing application sandboxing techniques.
- Reviewing and hardening system configurations related to GPU access controls.
