CVE-2026-34196

Arbitrary physical-memory access via truncated GPU mapping

Published Jul 10, 2026 · Updated Jul 10, 2026

Use-after-free in Imagination Technologies Graphics DDK through 26.1 RTM1 allows local users to read or write physical memory. PMRDevPhysAddrOSMem truncates an address calculation, mapping two GPU virtual addresses to one physical page; freeing one mapping releases the page while the other still references it. Non-privileged local software must issue crafted GPU system calls, after which another process's reuse of the page exposes its contents to reads and writes.
