CVE-2018-8043
Published: 10 March 2018
The unimac_mdio_probe function in drivers/net/phy/mdio-bcm-unimac.c in the Linux kernel through 4.15.8 does not validate certain resource availability, which allows local users to cause a denial of service (NULL pointer dereference).
From the Ubuntu security team
It was discovered that the Broadcom UniMAC MDIO bus controller driver in the Linux kernel did not properly validate device resources. A local attacker could use this to cause a denial of service (system crash).
