  3. CVE-2024-44940
In the Linux kernel, the following vulnerability has been resolved: fou: remove warn in gue_gro_receive on unsupported protocol Drop the WARN_ON_ONCE inn gue_gro_receive if the encapsulated type is not known or does not have a GRO handler. Such a packet is easily constructed. Syzbot generates them and sets off this warning. Remove the warning as it is expected and not actionable. The warning was previously reduced from WARN_ON to WARN_ON_ONCE in commit 270136613bf7 ("fou: Do WARN_ON_ONCE in gue_gro_receive for bad proto callbacks").

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: fou: elimine la advertencia en gue_gro_receive en un protocolo no compatible. Descarte WARN_ON_ONCE en gue_gro_receive si el tipo encapsulado no se conoce o no tiene un controlador GRO. Un paquete de este tipo se construye fácilmente. Syzbot los genera y activa esta advertencia. Elimine la advertencia como se esperaba y no es procesable. La advertencia se redujo previamente de WARN_ON a WARN_ON_ONCE en el commit 270136613bf7 ("fou: Haga WARN_ON_ONCE en gue_gro_receive para devoluciones de llamadas de proto incorrectas").
