Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An out-of-bounds read exists in the b43legacy rx() function within the b43legacy WiFi driver. The firmware-controlled key index can exceed the dev->max nr keys limit. Because the existing warning mechanism is non-enforcing in production builds, it allows an out-of-bounds read of the dev->key[] array.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
