Local privilege escalation via Crash Reporter logic
Published Apr 2, 2021 · Updated Aug 3, 2024
Logic errors in Apple Crash Reporter in iOS and iPadOS before 14.4 and macOS Big Sur before 11.2 allow local users to elevate privileges. Apple identifies multiple faulty logic paths in Crash Reporter but has not published the affected functions, attacker-controlled inputs, or incorrect operations. Exploitation requires local code execution or session access, and the disclosed consequence is privilege elevation rather than remote compromise.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
