Overview
What is CVE-2026-99048?
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.
