Descriptions
An issue was discovered in the Linux kernel before 5.0. The function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free. This will cause a denial of service.
Fue encontrado un problema en el kernel de Linux anterior a versión 5.0. La función __mdiobus_register() en el archivo drivers/net/phy/mdio_bus.c llama a put_device(), que desencadenará un uso después de liberar de fix_mdio_bus_init . Esto causará una denegación de servicio.
A use-after-free flaw was found in the Linux kernel's MDIO section of the network management subsystem. An attacker who is able to hot-plug a network device can trigger the __mdiobus_register() function in drivers/net/phy/mdio_bus.c, which can cause a use-after-free condition causing a memory corruption and kernel panic or privilege escalation.
