Descriptions
In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/class/cdc-acm.c driver, aka CID-c52873e5a1ef.
En el kernel de Linux versiones anteriores a 5.2.10, se presenta un bug de uso de la memoria previamente liberada que puede ser causado por un dispositivo USB malicioso en el controlador del archivo drivers/usb/class/cdc-acm.c, tambiƩn se conoce como CID-c52873e5a1ef.
A use-after-free flaw was found in the acm_probe USB subsystem in the Linux kernel. A race condition occurs when a destroy() procedure is initiated allowing the refcount to decrement on the interface so early that it is never under counted. A malicious USB device is required for exploit. System availability is the largest threat from the vulnerability, however data integrity and confidentiality are also threatened.
