Name of the Vulnerable Software and Affected Versions Linux kernel versions 4.9.x through 4.10.1

Description The issue is caused by incorrect interaction with the CONFIG VMAP STACK option in the drivers/net/can/usb/gs usb.c file, allowing local users to cause a denial of service, such as a system crash or memory corruption, by leveraging the use of more than one virtual page for a DMA scatterlist. This is also described as a buffer overflow vulnerability in memory, which can be exploited by a local attacker to potentially have unspecified other impact.

Recommendations For Linux kernel versions 4.9.x through 4.10.1, update to version 4.10.2 or later to resolve the issue.
