CVE-2024-46716
Altera MSGDMA Linux Kernel DMA Engine Use-After-Free Vulnerability
Description
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.
