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.

CVE-2018-13053 [LOW] Linux kernel (AWS) vulnerabilities
Title: Linux kernel (AWS) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the alarmtimer implementation in the Linux kernel
contained an integer overflow vulnerability. A local attacker could use
this to cause a denial of service. (CVE-2018-13053)
Wen Xu discovered that the XFS filesystem implementation in the Linux
kernel did not properly track inode validations. An attacker could use this
to construct a malicious XFS image that, when mounted, could cause a denial
of service (system crash). (CVE-2018-13093)

CVE-2019-12819 [MEDIUM] CWE-416 kernel: use-after-free in function __mdiobus_register() in drivers/net/phy/mdio_bus.c
kernel: use-after-free in function __mdiobus_register() in drivers/net/phy/mdio_bus.c
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.
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.

CVE-2019-12819 [MEDIUM] CVE-2019-12819 kernel: use-after-free in function __mdiobus_register() in drivers/net/phy/mdio_bus.c
CVE-2019-12819 kernel: use-after-free in function __mdiobus_register() in drivers/net/phy/mdio_bus.c
An issue was discovered in the Linux kernels implementation of Management Data Input/Output (MDIO) or SMI system.
An attacker who is able to hot-plug a network device can trigger the function
__mdiobus_register() in drivers/net/phy/mdio_bus.c which calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free. This will cause a denial of service.
While this function is also run during system boot with onboard networking hardware, exploiting the use-after-free during this narrow timeframe makes the exploit a non-trivial exercise.
