{"id":"DEBIAN-CVE-2021-47655","details":"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.
