In the Linux kernel, the following vulnerability has been resolved:
gve: fix napi disable deadlock when attempting to disable XSK pools
When disabling XSK pools, GVE calls the unlocked versions of
napi disable and napi enable. However, the netdev lock has already been
acquired before ndo bpf is called because GVE supports queue management
ops. Calling the unlocked versions of napi disable/enable results in a
deadlock when attempting to disable XSK pools, as the thread attempts to
re-acquire a lock it already holds.
Update the NAPI calls to use the locked versions.
This issue was found in production.
