Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a memory leak in the if usb probe handler of the Linux kernel's libertas driver. An attacker can exploit this by connecting a Marvell 8388 USB WLAN device with a wMaxPacketSize of 0x0 in its device descriptor. This causes memory to be allocated in the cardp variable within the if usb probe function, but when wMaxPacketSize is zero, the function jumps to an error label without freeing the allocated memory, potentially leading to a denial of service.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
