Synopsis ========
A vulnerability in NVIDIA drivers may allow a local attacker to gain escalated privileges.
Background ==========
The NVIDIA drivers provide X11 and GLX support for NVIDIA graphic boards.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-drivers/nvidia-drivers < 295.40 >= 295.40
Description ===========
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.
Resolution ==========
All NVIDIA driver users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot -v ">=x11-drivers/nvidia-drivers-295.40"
