Descriptions
In the Linux kernel, the following vulnerability has been resolved: media: venus: vdec: fixed possible memory leak issue The venus_helper_alloc_dpb_bufs() implementation allows an early return
on an error path when checking the id from ida_alloc_min() which would
not release the earlier buffer allocation. Move the direct kfree() from the error checking of dma_alloc_attrs() to
the common fail path to ensure that allocations are released on all
error paths in this function. Addresses-Coverity: 1494120 ("Resource leak")
