CVE-2023-53079

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix steering rules cleanup vport's mc, uc and multicast rules are not deleted in teardown path when EEH happens. Since the vport's promisc settings(uc, mc and all) in firmware are reset after EEH, mlx5 driver will try to delete the above rules in the initialization path. This cause kernel crash because these software rules are no longer valid. Fix by nullifying these rules right after delete to avoid accessing any dangling pointers.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5: Se corrige la eliminación de las reglas de direccionamiento de las reglas de limpieza de vport mc, uc y multicast en la ruta de desmontaje cuando se produce EEH. Dado que la configuración promisc del vport (uc, mc y todas) en el firmware se restablece después de EEH, el controlador mlx5 intentará eliminar las reglas mencionadas en la ruta de inicialización. Esto provoca un fallo del kernel porque estas reglas de software ya no son válidas. Se corrige anulando estas reglas justo después de la eliminación para evitar el acceso a punteros colgantes.
