CVE-2026-45200: CWE-416: Use After Free in Imagination Technologies Graphics DDK
Description
Software installed and run as a non-privileged user may conduct improper GPU driver IOCTL calls to create an allocation scenario that when freed would cause double free and kernel heap corruption. Scenario caused by fabricating a specific combination of flags on the allocation interface that would cause an incorrect double free event when freed.

Technical Analysis
This vulnerability (CVE-2026-45200) in Imagination Technologies Graphics DDK involves a use-after-free condition (CWE-416) triggered by non-privileged users through crafted GPU driver IOCTL calls. By fabricating a specific combination of flags on the allocation interface, an incorrect double free event occurs when the allocation is freed, leading to kernel heap corruption. This flaw can be exploited to compromise system stability and security at the kernel level.
Potential Impact
Successful exploitation can lead to kernel heap corruption, potentially allowing an attacker to execute arbitrary code with kernel privileges, causing system crashes or escalation of privileges. The CVSS score of 7.8 indicates high impact on confidentiality, integrity, and availability. However, no known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided at this time. Until a patch is available, restrict access to the vulnerable GPU driver interfaces to trusted users only and monitor for suspicious activity related to GPU driver IOCTL calls.
