CVE-2024-38562 is an out-of-bounds array-indexing flaw in the Linux kernel nl80211 Wi-Fi subsystem. The affected code can use request->channels[] before request->n_channels has been initialized and performs address calculations for memory beyond the channels array through an out-of-bounds array index rather than from the request allocation base. The correction initializes the channel count before use and derives subsequent addresses from the allocation base.
