Official description
In the Linux kernel, the following vulnerability has been resolved: staging: vt6655: fix potential memory leak In function device_init_td0_ring, memory is allocated for member td_info of priv->apTD0Rings[i], with i increasing from 0. In case of allocation failure, the memory is freed in reversed order, with i decreasing to 0. However, the case i=0 is left out and thus memory is leaked. Modify the memory freeing loop to include the case i=0.
