In the Linux kernel, the following vulnerability has been resolved:

misc: fastrpc: Fix dma_buf object leak in fastrpc_map_lookup

In fastrpc_map_lookup, dma_buf_get is called to obtain a reference to

the dma_buf for comparison purposes. However, this reference is never

ensuring that the temporarily acquired reference is properly released

regardless of whether a matching map is found.

Rule: add
