The remote host is affected by the vulnerability described in GLSA-201206-19 (NVIDIA Drivers: Privilege escalation)
A vulnerability has been found in the way NVIDIA drivers handle read/write access to GPU device nodes, allowing access to arbitrary system memory locations.
NOTE: Exposure to this vulnerability is reduced in Gentoo due to 660 permissions being used on the GPU device nodes by default.
Impact :
A local attacker could gain escalated privileges.
Workaround :
There is no known workaround at this time.
