- Details

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 WARNON must be used to denote kernel bugs and not to print simple warnings. A warning can simply be printed using prwarn.
