Name of the Vulnerable Software and Affected Versions Linux kernel versions 4.9.x and 4.10.x before 4.10.12

Description The issue is caused by incorrect interaction with the CONFIG VMAP STACK option in the Linux kernel, 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 due to a buffer overflow in memory.
