About this tag
CVE-2026-43267 is a Linux kernel vulnerability disclosed on May 6, 2026, in the Realtek rtw89 Wi-Fi driver. Discovered during fuzz testing, a zero beacon interval could trigger a division-by-zero fault in beacon tracking code. The fix is minimal: if the driver sees a beacon interval of zero, it falls back to 100 TU, the ordinary Wi-Fi default. This tag covers discussions about the vulnerability, its patch, and the broader implications for kernel security when hardware-adjacent code encounters malformed state.
