Descriptions
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.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: batman-adv: Evite comprobaciones relacionadas con el tiempo WARN_ON. La interfaz soft/batadv para un MDS en cola se puede cambiar durante el tiempo que el MDS estuvo en cola para transmisión y cuando el MDS realmente se transmite por el trabajador. Pero WARN_ON debe usarse para indicar errores del kernel y no para imprimir simples advertencias. Una advertencia se puede imprimir simplemente usando pr_warn.
