CVE-2026-46163

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