In the Linux kernel, the following vulnerability has been resolved:
serial: max3100: Lock port->lock when calling uarthandlects_change()
uarthandlects_change() has to be called with port lock taken, Since we run it in a separate work, the lock may not be taken at the time of running. Make sure that it's taken by explicitly doing that. Without it we got a splat:
WARNING: CPU: 0 PID: 10 at drivers/tty/serial/serialcore.c:3491 uarthandlectschange+0xa6/0xb0 ... Workqueue: max3100-0 max3100work [max3100] RIP: 0010:uarthandlectschange+0xa6/0xb0 ... max3100handlerx+0xc5/0x110 [max3100] max3100work+0x12a/0x340 [max3100]
