"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nserial: 8250_bcm7271: fix use-after-free in brcmuart_remove()\n\nbrcmuart_handle_irq() starts priv->hrt to work around a receive-timeout\nquirk of the 8250 core when hardware flow control is enabled; the timer\ncallback brcmuart_hrtimer_func() dereferences priv.\n\nbrcmuart_remove() cancels the hrtimer before it unregisters the port, so\na receive-timeout interrupt that arrives in between re-arms the timer.\nAfter devm frees priv, the callback runs on freed memory.\n\nUnregister the port before cancelling the hrtimer.\nserial8250_unregister_port() shuts the port down and frees its IRQ, so\nbrcmuart_handle_irq() can no longer restart the timer, and the final\nhrtimer_cancel() drains any timer that was armed before or during the\nunregister.\n\nThis issue was found by an in-house static analysis tool."
