Arbitrary code execution via CSV path overflow
Published Mar 24, 2026 · Updated Mar 24, 2026
Out-of-bounds write in AIDA64 Extreme 5.99.4900 allows local users to execute arbitrary code through a crafted CSV log file path. The Hardware Monitoring logging preference accepts an oversized path and overwrites the structured exception handler with attacker-controlled bytes. Access to the local preferences interface is required, and execution occurs in the application's process when the saved path is processed during exit.
