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

dmaengine: tegra-adma: Fix use-after-free

A use-after-free bug exists in the Tegra ADMA driver when audio streams are terminated, particularly during XRUN conditions. The issue occurs when the DMA buffer is freed by tegra_adma_terminate_all() before the vchan completion tasklet finishes accessing it.

The race condition follows this sequence:

  • DMA transfer completes, triggering an interrupt that schedules the
completion tasklet (tasklet has not executed yet)
  • Audio playback stops, calling tegra_adma_terminate_all() which
frees the DMA buffer memory via kfree()
  • The scheduled tasklet finally executes, calling vchan_complete()
which attempts to access the already-freed memory

Since tasklets can execute at any time after being scheduled, there is no guarantee that the buffer will remain valid when vchan_complete() runs.

Fix this by properly synchronizing the virtual channel completion:

  • Calling vchan_terminate_vdesc() in tegra_adma_stop() to mark the
descriptors as terminated instead of freeing the descriptor.
  • Add the callback tegra_adma_synchronize() that calls
vchan_synchronize() which kills any pending tasklets and frees any terminated descriptors.
