A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in NVIDIA graphics drivers.

Software Description:
- nvidia-graphics-drivers-390: NVIDIA binary X.Org driver
- nvidia-graphics-drivers-450-server: NVIDIA server driver
- nvidia-graphics-drivers-470: NVIDIA binary X.Org driver
- nvidia-graphics-drivers-470-server: NVIDIA server driver
- nvidia-graphics-drivers-510: NVIDIA binary X.Org driver
- nvidia-graphics-drivers-510-server: NVIDIA server driver
- nvidia-graphics-drivers-515: NVIDIA binary X.Org driver
- nvidia-graphics-drivers-515-server: NVIDIA server driver

Details:

Le Wu discovered that the NVIDIA graphics drivers did not properly perform
input validation in some situations. A local user could use this to cause a
denial of service or possibly execute arbitrary code. (CVE-2022-31607)

Tal Lossos discovered that the NVIDIA graphics drivers incorrectly handled
certain memory operations, leading to a null-pointer dereference. A local
attacker could use this to cause a denial of service. (CVE-2022-31615)

Artem S. Tashkinov discovered that the NVIDIA graphics drivers Dynamic
Boost D-Bus component did not properly restrict access to its endpoint.
When enabled in non-default configurations, a local attacker could use this
to cause a denial of service or possibly execute arbitrary code.
(CVE-2022-31608)
