CVE-2026-50217 Akamai CVE debrief

Who should care

Akamai Guardicore Platform Agent users, particularly those with local low-privileged users, should assess exposure and prioritize patching or verification. Users should review the official advisory and CVE record to validate affected scope, severity, and vendor guidance.

Why it matters

CVE-2026-50217 is a medium-severity vulnerability in Akamai Guardicore Platform Agent that allows local low-privileged users to cause a denial of service. Users should assess exposure and prioritize patching or verification.

• Denial of service (system crash / BSOD) via local low-privileged user
• Potential for kernel pool grooming via attacker-controlled packet length

Technical summary

The vulnerability exists in the Windows WFP callout driver of Akamai Guardicore Platform Agent (GPA). A local low-privileged user can exploit this vulnerability by sending an outbound ICMPv6 packet containing an IPv6 Hop-by-Hop extension header, which can cause a denial of service (system crash / BSOD). 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. The vulnerability affects Akamai Guardicore Platform Agent users, particularly those with local low-privileged users.

Defensive priority

Medium-priority patching and verification recommended for Akamai Guardicore Platform Agent users.

• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
