CVE-2017-12146

Published: 8 September 2017

The driver_override implementation in drivers/base/platform.c in the Linux kernel before 4.12.1 allows local users to gain privileges by leveraging a race condition between a read operation and a store operation that involve different overrides.

From the Ubuntu Security Team

Yonggang Guo discovered that a race condition existed in the driver subsystem in the Linux kernel. A local attacker could use this to possibly gain administrative privileges.
