In the Linux kernel, the following vulnerability has been resolved: vduse: fix NULL pointer dereference vduse_vdpa_set_vq_affinity callback can be called with NULL value as cpu_mask when deleting the vduse device. This patch resets virtqueue's IRQ affinity mask value to set all CPUs instead of dereferencing NULL cpu_mask.
