CVE-2020-0110

A flaw was found in the Pressure stall information subsystem. This flaw allows a local attacker with the ability to write to root-owned files to corrupt kernel stack memory.

Mitigation

As the attacker must have the ability to write to these files, a possible mitigation would be to reduce the access that users and their processes would have to the files used in the attack. The files within the /proc/ filesystem can be temporarily modified with the chmod/chown command for each boot.
