CVE-2026-46122

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-&gt;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.
