CVE-2026-41155

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.
