Description

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

• linux linux kernel (>= 5.4 < 5.4.293) • linux linux kernel (>= 5.5 < 5.10.237) • linux linux kernel (>= 5.11 < 5.15.181) • linux linux kernel (>= 5.16 < 6.1.136) • linux linux kernel (>= 6.2 < 6.6.89) • linux linux kernel (>= 6.7 < 6.12.26) • linux linux kernel (>= 6.13 < 6.14.5) • linux linux kernel 6.15 • debian debian linux 11.0
