A fix is available in the Linux kernel versions identified by the fixed commit hashes. Users should update to a kernel version that includes these fixes to remediate the vulnerability. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's virtio_input driver was fixed by ensuring callbacks stop before the input device is unregistered. The issue involved callbacks potentially accessing freed input device structures due to improper synchronization during device removal. The fix involves resetting the device first and waiting for callbacks to complete before unregistering the input device, preventing use-after-free conditions.
