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.
