Kernel-memory disclosure or system crash via out-of-bounds read
Published Sep 8, 2021 · Updated Aug 3, 2024
Out-of-bounds read in Intel Graphics Driver on affected macOS releases allows local users to read kernel memory or crash the system. Vulnerable Intel Graphics Driver code performs an out-of-bounds read; Apple disclosed no triggering operation or data structure and removed that code. Exploitation requires local access, and the documented consequences are limited to kernel-memory disclosure or unexpected system termination.
