  3. CVE-2022-48926
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).

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: usb: gadget: rndis: agregar spinlock para la lista de respuestas de rndis No hay bloqueo para la lista de respuestas de rndis. Podría causar corrupción en la lista si hay dos list_add diferentes al mismo tiempo, como se muestra a continuación. Es mejor agregar rndis_add_response / rndis_free_response / rndis_get_next_response para evitar cualquier condición de ejecución en la lista de respuestas. [ 361.894299] [1: irq/191-dwc3:16979] list_add corrupción. siguiente->anterior debería ser anterior (ffffff80651764d0), pero era ffffff883dc36f80. (siguiente=ffffff80651764d0).
