How to fix?

Upgrade SLES:15.4 kernel-default-base to version 5.14.21-150400.24.141.1.150400.24.68.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-base package and not the kernel-default-base package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

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

dmaengine: altera-msgdma: properly free descriptor in msgdma_free_descriptor

Remove list_del call in msgdma_chan_desc_cleanup, this should be the role of msgdma_free_descriptor. In consequence replace list_add_tail with list_move_tail in msgdma_free_descriptor.

This fixes the path: msgdma_free_chan_resources -> msgdma_free_descriptors -> msgdma_free_desc_list -> msgdma_free_descriptor

which does not correctly free the descriptors as first nodes were not removed from the list.
