Kernel-memory disclosure via GPU driver out-of-bounds read
Published Mar 31, 2025 · Updated Jun 23, 2026
An out-of-bounds read in macOS GPU Drivers allows local users to disclose kernel memory through a locally run app. Apple identifies deficient bounds checks in GPU Drivers but has not published the affected function, input, or read operation. Exploitation requires executing an app on the Mac; the reported consequence is disclosure of kernel memory.
