- Details
-
In the Linux kernel, the following vulnerability has been resolved:
gve: guard XDP xmit NDO on existence of xdp queues
In GVE, dedicated XDP queues only exist when an XDP program is installed and the interface is up. As such, the NDO XDP XMIT callback should return early if either of these conditions are false.
In the case of no loaded XDP program, priv->numxdpqueues=0 which can cause a divide-by-zero error, and in the case of interface down, numxdpqueues remains untouched to persist XDP queue count for the next interface up, but the TX pointer itself would be NULL.
The XDP xmit callback also needs to synchronize with a device transitioning from open to close. This synchronization will happen via the GVEPRIVFLAGSNAPIENABLED bit along with a synchronize_net() call, which waits for any RCU critical sections at call-time to complete.
