Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: Fix memory leak in rtw88_usb
Kmemleak shows the following leak arising from routine in the usb probe routine:
The leak was verified to be real by unloading the driver, which resulted in a dangling pointer to the allocation.
The allocated memory is freed in rtw_usb_intf_deinit().
