Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: mdio: validar el parámetro addr en mdiobus_get_phy(). El llamador puede pasar cualquier valor como addr, lo que puede resultar en un acceso fuera de límites a la matriz mdio_map. Un caso existente es stmmac_init_phy(), que puede pasar -1 como addr. Por lo tanto, valide addr antes de usarlo.
