Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: cdns3: Fix deadlock when using NCM gadget<br /> <br /> The cdns3 driver has the same NCM deadlock as fixed in cdnsp by commit<br /> 58f2fcb3a845 ("usb: cdnsp: Fix deadlock issue during using NCM gadget").<br /> <br /> Under PREEMPT_RT the deadlock can be readily triggered by heavy network<br /> traffic, for example using "iperf --bidir" over NCM ethernet link.<br /> <br /> The deadlock occurs because the threaded interrupt handler gets<br /> preempted by a softirq, but both are protected by the same spinlock.<br /> Prevent deadlock by disabling softirq during threaded irq handler.
