CVE-2022-48926

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: gadget: rndis: add spinlock for rndis response list<br /> <br /> There&amp;#39;s no lock for rndis response list. It could cause list corruption<br /> if there&amp;#39;re two different list_add at the same time like below.<br /> It&amp;#39;s better to add in rndis_add_response / rndis_free_response<br /> / rndis_get_next_response to prevent any race condition on response list.<br /> <br /> [ 361.894299] [1: irq/191-dwc3:16979] list_add corruption.<br /> next-&gt;prev should be prev (ffffff80651764d0),<br /> but was ffffff883dc36f80.
