CVE-2026-46122

In the Linux kernel, the following vulnerability has been resolved:

wifi: b43: enforce bounds check on firmware key index in b43_rx()

The firmware-controlled key index in b43_rx() can exceed the dev->key[]
array size (58 entries). The existing B43_WARN_ON is non-enforcing in
production builds, allowing an out-of-bounds read.

Make the B43_WARN_ON check enforcing by dropping the frame when the
firmware returns an invalid key index.
