CVE-2022-48926
影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: rndis: add spinlock for rndis response list
There's no lock for rndis response list. It could cause list corruption
if there're two different list_add at the same time like below.
It's better to add in rndis_add_response / rndis_free_response
/ rndis_get_next_response to prevent any race condition on response list.
[ 361.894299] [1: irq/191-dwc3:16979] list_add corruption.
next->prev should be prev (ffffff80651764d0),
but was ffffff883dc36f80. (next=ffffff80651764d0).
