CVE-2017-12146
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
