vGPU software (guest driver - Linux), vGPU…: Out-of-bounds Write
CVE-2023-0183 is a high-severity out-of-bounds write vulnerability in vGPU software (guest driver - Linux), vGPU software (Virtual GPU Manager - Citrix Hypervisor, VMware vSphere, Red Hat Enterprise Linux KVM), NVIDIA Cloud Gaming (guest driver - Linux), NVIDIA Cloud Gaming (Virtual GPU Manager - Red Hat Enterprise Linux KVM) from NVIDIA, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. There is no confirmed exploitation so far. EPSS estimates a 0.24% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Virtual GPU to 11.12 or 13.7 or 15.2, whichever matches your release line, or a later version.
- Read the advisory on nvidia.custhelp.com for workarounds and exact fixed builds.

Official description
NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer where an out-of-bounds write can lead to denial of service and data tampering.

The underlying weakness: Out-of-bounds Write
The product writes data past the end, or before the beginning, of the intended buffer.
How developers prevent this class of flaw
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow protection, but the protection can be disabled by the programmer. Be wary that a language's interface to native code may still be subject to overflows, even if the language itself is theoretically safe.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Examples include the Safe C String Library (SafeStr) by Messier and Viega, and the Strsafe.h library from Microsoft. These libraries provide safer versions of overflow-prone string-handling functions.
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking. D3-SFCV (Stack Frame Canary Validation) from D3FEND discusses canary-based detection in detail.
