CVE-2026-43267 Details
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: fix potential zero beacon interval in beacon tracking During fuzz testing, it was discovered that bss_conf->beacon_int might be zero, which could result in a division by zero error in subsequent calculations. Set a default value of 100 TU if the interval is zero to ensure stability.
A vulnerability in the Linux kernel's Realtek RTW89 wireless driver could lead to a division by zero error. During fuzz testing, it was found that the beacon interval could be zero, potentially causing instability in beacon tracking. The issue has been addressed by setting a default beacon interval of 100 time units if the original interval is zero.
