In vmw_get_cap_3d_ioctl(), a user can supply 0 for a size that is used in vzalloc(). This eventually calls dump_stack() (in warn_alloc()), which can leak useful addresses to dmesg. Add check to avoid a size of 0. Cc: <stable@vger.kernel.org> Signed-off-by: Murray McAllister <murray.mcallister@insomniasec.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>
