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

serial: amba-pl011: cancel RS485 hrtimers after freeing IRQ

The RS485 trigger hrtimers are embedded in the devm-managed port and can

fire after it is freed. The IRQ handler can arm a timer, so free the IRQ

first and then cancel both timers.

Complete the RS485 stop without arming a timer, and cancel the timers

in remove() for the suspend-then-unbind path, where shutdown is not

called.

This issue was found by an in-house static analysis tool. (NVD)
