CVE-2026-28935

System termination or kernel corruption via memory mishandling

Published Sep 14, 2026 · Updated Sep 14, 2026

Memory-handling flaw in the Apple kernel across affected platforms allows local apps to terminate the system or corrupt kernel memory. Apple has not disclosed the affected kernel component or the incorrect memory operation beyond stating that improved memory handling addressed the issue. Exploitation requires an app to execute locally; the bounded outcomes are a system crash or kernel-memory corruption, with no published claim of code execution.
