Description
A flaw was found in the Google Virtual Ethernet (gve) driver in the Linux kernel. When stopping network queues and resetting the ring state, the driver fails to release eXpress Data Path socket (XSK) buffers posted to the network interface. A local user with network administrative privileges can trigger this issue by reconfiguring or stopping queues, leading to a memory leak and a potential Denial of Service (DoS) due to resource exhaustion.
