{"id":"CVE-2026-50217","published":"2026-10-14T06:17:06.760","lastModified":"2026-10-16T19:55:59.740","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.","cvssScore":4.7,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-416"],"vendors":[],"products":[],"references":[{"url":"https://techdocs.akamai.com/guardicore-platform-agent/changelog/","tags":[]},{"url":"https://www.akamai.com/newsroom/security-advisories/guardicore-platform-agent-7-4","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
