Descriptions
drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-space client to corrupt the monitor's internal memory.
El archivo drivers/usb/mon/mon_bin.c en usbmon en el kernel de Linux versiones anteriores a 5.19.15 y versiones 6.x anteriores a 6.0.1, permite que un cliente del espacio de usuario corrompa la memoria interna del monitor
An out-of-bounds memory write flaw in the Linux kernel’s USB Monitor component was found in how a user with access to the /dev/usbmon can trigger it by an incorrect write to the memory of the usbmon. This flaw allows a local user to crash or potentially escalate their privileges on the system.
