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

dmaengine: idxd: fix possible wrong descriptor completion in llist_abort_desc()

At the end of this function, d is the traversal cursor of flist, but the

code completes found instead. This can lead to issues such as NULL pointer

dereferences, double completion, or descriptor leaks.

Fix this by completing d instead of found in the final

list_for_each_entry_safe() loop. (NVD)
