CVE-2026-45195

Host memory access via untrusted firmware fault address

Published Jun 26, 2026 · Updated Jun 26, 2026

Improper privilege handling in Imagination Technologies Graphics DDK allows local users to read or write memory beyond host-kernel limits. The GPU firmware trusts the sFaultPhysAddr value passed to rgxfw_set_mips_fault_address and uses it for accesses with privileges unavailable to the host kernel. The path requires low-privilege kernel software inside a Host VM and affects 1.18 RTM, 23.2 RTM, 24.2 RTM, 25.1 RTM through 25.3 RTM, and 26.1 RTM.
