What is CVE-2026-41157?
CVE-2026-41157 is a critical memory corruption vulnerability in Imagination Technologies Graphics DDK, published on 12 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
A web page that contains unusual WebGPU content loaded into the GPU GLES render process and can trigger an out-of-bound write in the GPU user-space driver, leading to memory corruption and possible browser/GPU process crash.
The software computes a required memory size from untrusted input, but integer overflow can produce a value smaller than needed. Subsequent write operations may then occur past the intended memory boundary, corrupting adjacent memory and causing process instability or termination.
Weakness: CWE-787
