NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_3_18-150300_59_161-default package and not the kernel-livepatch-5_3_18-150300_59_161-default package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

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

dmaengine: idxd: Fix possible Use-After-Free in irq_process_work_list

Use list_for_each_entry_safe() to allow iterating through the list and deleting the entry in the iteration process. The descriptor is freed via idxd_desc_complete() and there's a slight chance may cause issue for the list iterator when the descriptor is reused by another thread without it being deleted from the list.
