Technical details

An integer underflow in the macOS NetworkExtension system extension's DNS proxy component occurs when processing UDP datagrams shorter than 96 bytes with a specific starting value. The size computation underflows to near SIZE_MAX, triggering a memory allocation failure and uncaught Objective-C exception that terminates the root system extension.
