CVE-2022-22630Network attack vector

Unauthenticated code execution via AppleEvents use-after-free

Published Jun 23, 2023 · Updated Dec 6, 2024

Use-after-free in AppleEvents in Apple macOS allows remote attackers to execute code or terminate the AEServer process. Apple Remote Events fails to validate user-supplied data before memory handling, producing memory corruption in AEServer. Network reachability is sufficient; exploitation requires no authentication or user interaction and runs code in the AEServer context.
