CVE-2022-48949

In the Linux kernel, the following vulnerability has been resolved: igb: Initialize mailbox message for VF reset When a MAC address is not assigned to the VF, that portion of the message sent to the VF is not set. The memory, however, is allocated from the stack meaning that information may be leaked to the VM. Initialize the message buffer to 0 so that no information is passed to the VM in this case.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: igb: inicializar mensaje de buzón para restablecer VF Cuando no se asigna una dirección MAC a la VF, esa parte del mensaje enviado a la VF no se configura. Sin embargo, la memoria se asigna desde la pila, lo que significa que la información puede filtrarse a la VM. Inicialice el búfer de mensajes a 0 para que no se pase información a la VM en este caso.
