Harshit Mogalapalli 308d24d875 vduse: Validate vq_num in vduse_validate_config() ... [ Upstream commit 937c783aa3 ] Add a limit to 'config->vq_num' which is user controlled data which comes from an vduse_ioctl to prevent large memory allocations. Micheal says - This limit is somewhat arbitrary. However, currently virtio pci and ccw are limited to a 16 bit vq number. While MMIO isn't it is also isn't used with lots of VQs due to current lack of support for per-vq interrupts. Thus, the 0xffff limit on number of VQs corresponding to a 16-bit VQ number seems sufficient for now. This is found using static analysis with smatch. Suggested-by: Michael S.
