Secure-process disruption via globally mapped shared memory
Published Jun 12, 2026 · Updated Jun 12, 2026
Improper isolation in Imagination Technologies Graphics DDK allows local users to disrupt other secure GPU processes. SharedSecMem allocations are mapped into every GPU virtual address space instead of being isolated to their owning secure process. Low-privileged local code with access to a secure GPU process can corrupt shared resources, causing image corruption or GPU hardware recovery; colluding secure processes can also exchange data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=1.18 RTM
- Affected versionversion=23.2 RTM
- Affected versionversion=24.2 RTM
- Affected versionversion=25.1 RTM <=25.3 RTM
