- wifi: cfg80211: Set correct chandef when starting CAC
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: Set correct chandef when starting CAC
When starting CAC in a mode other than AP mode, it return a "WARNING: CPU: 0 PID: 63 at cfg80211_chandef_dfs_usable+0x20/0xaf [cfg80211]" caused by the chandef.chan being null at the end of CAC.
Solution: Ensure the channel definition is set for the different modes when starting CAC to avoid getting a NULL 'chan' at the end of CAC.
