Title
wifi: rtw89: fix potential zero beacon interval in beacon tracking
Summary
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.
Severity ?
No CVSS data available.
