Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: b43: enforce bounds check on firmware key index in b43_rx()<br />
<br />
The firmware-controlled key index in b43_rx() can exceed the dev->key[]<br />
array size (58 entries). The existing B43_WARN_ON is non-enforcing in<br />
production builds, allowing an out-of-bounds read.<br />
<br />
Make the B43_WARN_ON check enforcing by dropping the frame when the<br />
firmware returns an invalid key index.
