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.
Affected configurations
• linux linux kernel (< 6.1.109)
• linux linux kernel (>= 6.2 < 6.6.50)
• linux linux kernel (>= 6.7 < 6.10.9)
