Apple M1 GPUs retain register file data between compute shader dispatches from different processes. A sandboxed Metal attacker app can run a GPU reader shader that reads stale register values left by a separate sandboxed victim app. In the proof of concept, GPUVictim.app generates a fresh random...

CVE-2026-49269

Apple M1 GPUs expose a cross-process register state leakage: a sandboxed Metal attacker can read stale values from another sandboxed process’s compute shader dispatches, potentially recovering a 128-bit secret that was loaded into GPU registers. In proof-of-concept, a victim app writes a fresh se...
