Description
Software installed and run as a non-privileged user may conduct GPU system calls which cause GPU memory leaks and possible kernel heap corruption.



Scenario caused by memory free paths not maintaining state data of upgraded higher order allocations. This could cause memory leak or double free event.

Impact

A vulnerability in Imagination Technologies' Graphics DDK allows a non-privileged user to perform GPU system calls that ultimately trigger memory leaks and double free events. These improper deallocation paths can lead to kernel heap corruption, potentially destabilizing the operating system or allowing an attacker to gain additional write or execute privileges within kernel memory.

Affected Systems

Imagination Technologies Graphics DDK is the affected product. Detailed version information was not provided, so any installation of the Graphics DDK may be vulnerable until an official patch is released.

Risk and Exploitability

The CVSS score of 5.5 indicates a medium severity for this kernel heap corruption flaw, and the EPSS score of less than 1% suggests that exploitation is unlikely at present. Nevertheless, any unpatched system that accepts GPU calls from untrusted users remains at risk, as the double‑free and memory‑leak conditions could cause kernel memory corruption and potential escalation.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Contact Imagination Technologies to obtain the earliest patch or firmware update that addresses the double free and memory leak in Graphics DDK.
  • Configure the system to restrict GPU system call access to privileged processes only; deny or limit non‑privileged user interaction with the graphics driver.
  • Enable kernel hardening features such as KASLR, lockdown, and memory protection to reduce the impact of any residual heap corruption.
  • Regularly monitor kernel and system logs for abnormal OOPS, memory corruption, or crash signatures that could indicate exploitation attempts.
