  "details": "In the Linux kernel, the following vulnerability has been resolved:  serial: 8250_bcm7271: fix use-after-free in brcmuart_remove()  brcmuart_handle_irq() starts priv-\u003ehrt to work around a receive-timeout quirk of the 8250 core when hardware flow control is enabled; the timer callback brcmuart_hrtimer_func() dereferences priv.  brcmuart_remove() cancels the hrtimer before it unregisters the port, so a receive-timeout interrupt that arrives in between re-arms the timer. After devm frees priv, the callback runs on freed memory.  Unregister the port before cancelling the hrtimer. serial8250_unregister_port() shuts the port down and frees its IRQ, so brcmuart_handle_irq() can no longer restart the timer, and the final hrtimer_cancel() drains any timer that was armed before or during the unregister.  This issue was found by an in-house static analysis tool.",
