MEDIUM 4.9EPSS 0.35%

Does this matter?

Lower severity and a low EPSS score (0.35%). Track it; it rarely justifies an emergency change on its own.

Description

A buffer overflow was addressed with improved bounds checking. This issue is fixed in Xcode 26.1. A user in a privileged network position may be able to cause a denial-of-service.
