Detailsinfo

A vulnerability classified as critical was found in Apple M1 (affected version unknown). This vulnerability affects an unknown functionality. The manipulation with an unknown input leads to a sandbox vulnerability. The CWE definition for the vulnerability is CWE-265. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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 128-bit secret using SecRandomCopyBytes and loads it into GPU registers. GPUAttacker.app, a separate sandboxed app, recovers the exact secret from stale GPU register state. NOTE: The vendor stated that this behavior affects only legacy hardware and has already been addressed at the hardware level in current-generation Apple Silicon.

The advisory is shared for download at gist.github.com. This vulnerability was named CVE-2026-49269 since 05/28/2026. The exploitation appears to be easy. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 06/24/2026).
