What to Know

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

serial: amba-pl011: synchronize DMA teardown

dmaengine_terminate_all() does not wait for a running callback, so the TX

callback can still touch the TX buffer after it is freed. The RX poll

timer reads the RX buffers without the port lock.

Switch to dmaengine_terminate_sync() and delete the RX timer before

freeing the buffers. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
