CVE-2025-43375

Process crash via oversized path value

Published Sep 15, 2025 · Updated Sep 15, 2025

Denial of service in Apple Xcode before 26 allows attackers to crash a Dev Tools process by supplying an overly large path value. Apple has not disclosed the affected Dev Tools component or the specific path-processing check that accepts the oversized value. Published assessments disagree on local user interaction versus network reachability, but the documented consequence is limited to a process crash.
