Ubuntu 17.10 : Linux kernel vulnerability (USN-3630-1)

medium Nessus Plugin ID 109312

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
