drivers/input/serio/i8042.c in the Linux kernel before 4.12.4 allows attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated.
A flaw was found in the Linux kernel's implementation of i8042 serial ports. An attacker could cause a kernel panic if they are able to add and remove devices as the module is loaded.
Отчет
This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6, 7, its real-time kernel and Red Hat Enterprise MRG 2. At this time there are no plans to fix this issue. This issue does not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 7 for ARM 64 and Red Hat Enterprise Linux 7 for Power 9 LE.
