Vulnerability Description
A use-after-free vulnerability in the Windows WFP callout driver of Akamai Guardicore Platform Agent (GPA) allows a local low-privileged user to cause a denial of service (system crash / BSOD) via an outbound ICMPv6 packet containing an IPv6 Hop-by-Hop extension header. When the IPv6 ICMP redirect policy is active, the packet is copied into a buffer that is freed but subsequently passed to a downstream filter. The size of the freed allocation is attacker-controlled (via packet length), enabling kernel pool grooming. Exploitation requires that the non-default IPv6 ICMP capture/redirect policy is enabled for the endpoint.
