CVE-2024-27826

Local system shutdown via memory-handling flaw

Published Jul 29, 2024 · Updated Apr 2, 2026

Memory-handling flaw in Apple Neural Engine across affected Apple platforms allows local users to cause an unexpected system shutdown. Apple states that improved memory handling corrected the issue but has not disclosed the affected routine, memory operation, or triggering input. Exploitation requires local execution on the device, and the vendor-documented consequence is a system shutdown.
