  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nserial: amba-pl011: cancel RS485 hrtimers after freeing IRQ\n\nThe RS485 trigger hrtimers are embedded in the devm-managed port and can\nfire after it is freed. The IRQ handler can arm a timer, so free the IRQ\nfirst and then cancel both timers.\n\nComplete the RS485 stop without arming a timer, and cancel the timers\nin remove() for the suspend-then-unbind path, where shutdown is not\ncalled.\n\nThis issue was found by an in-house static analysis tool.",
