Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: b43legacy: enforce bounds check on firmware key index in RX path
Same fix as b43: the firmware-controlled key index in b43legacy_rx()
can exceed dev->max_nr_keys. The existing B43legacy_WARN_ON is
non-enforcing in production builds, allowing an out-of-bounds read of
dev->key[].
Make the check enforcing by dropping the frame for invalid indices.

• linux linux kernel (>= 2.6.24 < 5.10.258)
• linux linux kernel (>= 5.11 < 5.15.209)
