wi-fi driver bug

The wi-fi driver bug tag covers a specific security vulnerability in the Linux kernel's Broadcom b43 Wi-Fi driver, identified as CVE-2026-46122. This bug involves an out-of-bounds read caused by invalid firmware-controlled key indices in received frames. The fix rejects such frames to prevent potential exploitation. While the vulnerability is hardware-specific and affects older wireless chipsets, it highlights broader concerns about security debt in driver paths where firmware is trusted. For WindowsForum users running Linux on dual-boot systems, spare laptops, or routers, this tag provides information on kernel patches that address such driver-level bugs, emphasizing the importance of staying updated with kernel security fixes.
