CVE-2026-80737
Description
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.
