CVE-2026-21733
GPU DDK - Incorrect flags validation in RGXDerivePTEProt8 can allow GPU to overwrite read-only shared memory (e.g. libc.so)
Software installed and run as a non-privileged user may conduct improper GPU system calls to gain write permission to read-only wrapped user-mode memory and files.
This is caused by improper handling of GPU memory reservation protections.
