CVE-2026-99048

EUVD-2026-108843
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.
