"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ngve: fix napi_disable deadlock when attempting to disable XSK pools\n\nWhen disabling XSK pools, GVE calls the unlocked versions of\nnapi_disable and napi_enable. However, the netdev lock has already been\nacquired before ndo_bpf is called because GVE supports queue management\nops. Calling the unlocked versions of napi_disable/enable results in a\ndeadlock when attempting to disable XSK pools, as the thread attempts to\nre-acquire a lock it already holds.\n\nUpdate the NAPI calls to use the locked versions.\n\nThis issue was found in production."
