MediumCVSS 5.5/10Last modified Nov 11, 2026

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.
