What is CVE-2026-50216?

An integer underflow vulnerability in the DNS proxy component of the Akamai Guardicore Platform Agent for macOS has been identified. This issue occurs when a UDP datagram, shorter than 96 bytes and starting with a specific value, is processed. The resulting calculation underflows to a near-SIZE_MAX value, leading to an allocation failure. Consequently, this triggers an uncaught Objective-C exception that can cause the system extension to abort, potentially impacting system stability.

Affected Version(s)
