Описание
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.
It was found that the driver_override implementation in base/platform.c in the Linux kernel is susceptible to race condition when different threads are reading vs storing a different driver override.
Отчет
This issue does not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5, 6, 7 and MRG-2 as the code with the flaw is not present in the products listed.
