A fix is available — apply it.

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

dmaengine: mmp_pdma: Fix race condition in mmp_pdma_residue()

Add proper locking in mmp_pdma_residue() to prevent use-after-free when accessing descriptor list and descriptor contents.

The race occurs when multiple threads call tx_status() while the tasklet on another CPU is freeing completed descriptors:

CPU 0 CPU 1 ----- ----- mmp_pdma_tx_status() mmp_pdma_residue() -> NO LOCK held list_for_each_entry(sw, ..) DMA interrupt dma_do_tasklet() -> spin_lock(&desc_lock) list_move(sw->node, ...) spin_unlock(&desc_lock) | dma_pool_free(sw) <- FREED! -> access sw->desc <- UAF!

This issue can be reproduced when running dmatest on the same channel with multiple threads (threads_per_chan > 1).

Fix by protecting the chain_running list iteration and descriptor access with the chan->desc_lock spinlock.
