DescriptionAn integer underflow exists in the DNS proxy component of the macOS NetworkExtension system extension shipped with Akamai Guardicore Platform Agent (GPA) for macOS, whereby if a UDP datagram shorter than 96 bytes that begins with a specific value is received, a subsequent size computation underflows to a near-SIZE_MAX value, causing an allocation failure and uncaught Objective-C exception that aborts the root system extension.
