In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: Avoid address calculations via out of bounds array indexing
Before request->channels[] can be used, request->n_channels must be set.
Additionally, address calculations for memory after the "channels" array
need to be calculated from the allocation base ("request") rather than
via the first "out of bounds" index of "channels", otherwise run-time
bounds checking will throw a warning.
