Summary
CVE-2024-49937 affecting package kernel 5.15.200.1-1
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 cfg80211chandefdfs_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.
