NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150700_7_54-rt package and not the kernel-livepatch-6_4_0-150700_7_54-rt package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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.
