Ubuntu.comUB:CVE-2021-47252CVE-2021-47252
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.
