CVE-2020-3845

System-privilege code execution via driver memory corruption

Published Feb 27, 2020 · Updated Aug 4, 2024

Memory corruption in Apple’s Intel Graphics Driver in macOS Catalina 10.15.2 allows local users to execute code with system privileges. Apple identifies deficient memory handling in the Intel Graphics Driver, but has not disclosed the affected routine or malformed object that triggers corruption. Execution of a local application and user interaction are required; successful exploitation crosses the application boundary to system privileges.
