gpu: nvgpu: fix use of untrusted scalar value
Kind value can be passed to API nvgpu_vm_map() from User space (through IOCTL NVGPU_AS_IOCTL_MAP_BUFFER_EX) But kind value is not checked for sane values before storing it in bfr.kind_v And then we use this kind value as array index in gk20a_kind_is_supported() which is incorrect Fix this by ensuring in nvgpu_vm_map() that the kind value is well within range Bug 200291879 Coverity id : 2567923 Coverity id : 2567924 Change-Id: Ic57395018727cbd2260c929581db256e427316c6 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1496597 GVS: Gerrit_Virtual_Submit Reviewed-by: svccoveritychecker <svccoveritychecker@nvidia.com> Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
