Denial of service via CarPlay buffer overflow
Published May 8, 2023 · Updated Jan 29, 2025
Buffer overflow in CarPlay in Apple iOS and iPadOS before 16.4 allows remote attackers in a privileged network position to interrupt service. Apple identifies CarPlay as the locus and reports that missing bounds checks permit a buffer overflow, but it does not disclose the affected routine or input field. Reachability requires a privileged network position, and the reported consequence is limited to a denial-of-service interruption.

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.
