CVE-2021-47305 Description

In the Linux kernel, the following vulnerability has been resolved: dma-buf/sync_file: Don\'t leak fences on merge failure Each add_fence() call does a dma_fence_get() on the relevant fence. In the error path, we weren\'t calling dma_fence_put() so all those fences got leaked. Also, in the krealloc_array failure case, we weren\'t freeing the fences array. Instead, ensure that i and fences are always zero-initialized and dma_fence_put() all the fences and kfree(fences) on every error path.
