Description
The vulnerability allows a local user toobtain elevated privileges on the target system.
The weakness occurs in the kernel mode layer (nvidia.ko) handler for mmap() and exists due to improper input validation. By sending a specially crafted file, a local attacker can gain access to arbitrary physical memory, leading to an escalation of privileges.
Successful exploitation of the vulnerability results in privilege escalation.

Mitigation
Update Quadro, NVS and GeForce to 304.132, 340.98, 367.55, 370.28.
Update Tesla to 361.93.03, 367.55.
