CVE-2025-13952Network attack vector

GPU compiler crash via stale pointer write

Published Jan 24, 2026 · Updated Jan 24, 2026

Write use-after-free in libusc in Imagination Technologies Graphics DDK 25.1 RTM through 25.2 RTM allows remote attackers to crash GPU compilation. MergeConsecutiveBarriersBP retains an out-of-date pointer to a freed object and writes through it when compiling unusual WebGPU shader code. A crafted webpage must reach the GPU compiler; the immediate consequence is a compiler-process crash, while system-privileged compiler execution enables further device exploitation.
