A use-after-free vulnerability exists in the pushMuxer CreatePushThread functionality of Anker Eufy Homebase 2 2.1.6.9h. A specially-crafted set of network packets can lead to remote code execution.

Weakness

A product performs a series of non-atomic actions to switch between contexts that cross privilege or other security boundaries, but a race condition allows an attacker to modify or misrepresent the product’s behavior during the switch.
