CVE-2026-34192: CWE-416: Use After Free (4.15) in Imagination Technologies Graphics DDK
Software installed and run as a non-privileged user may conduct improper GPU system calls to cause an error path leading to UAF of GPU page tables. The vulnerability allows physical memory allocated for MMU page tables to be used after being freed. This was caused by an error path that would not cleanup properly before freeing the physical allocation.
AI Analysis
Technical Summary
This vulnerability involves a use-after-free (CWE-416) condition in the Imagination Technologies Graphics DDK. Specifically, an error path in GPU system call handling fails to properly clean up before freeing physical memory allocated for MMU page tables. As a result, the freed memory may be accessed afterward, which can lead to corruption or crashes. The issue affects non-privileged user software interacting with the GPU. No patch or official remediation has been disclosed, and no known exploits are reported in the wild.
Potential Impact
The vulnerability allows improper use of freed physical memory for GPU MMU page tables, which can cause integrity and availability impacts. According to the CVSS vector, there is no confidentiality impact, but integrity and availability impacts are high. This could result in GPU malfunction or system instability when exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been published. Users should monitor Imagination Technologies advisories for updates and apply patches once available.
