In the Linux kernel, the following vulnerability has been resolved:
batman-adv: Avoid WARN_ON timing related checks
The soft/batadv interface for a queued OGM can be changed during the time
the OGM was queued for transmission and when the OGM is actually
transmitted by the worker.
But WARN_ON must be used to denote kernel bugs and not to print simple
warnings. A warning can simply be printed using pr_warn.
