Description

- CVE-2021-1052 (privilege escalation)

The NVIDIA GPU Display Driver, all versions of the R460 and R450 driver
branches, contains a vulnerability in the kernel mode layer (nvidia.ko)
handler for DxgkDdiEscape or IOCTL in which user-mode clients can
access legacy privileged APIs, which may lead to denial of service,
escalation of privileges, and information disclosure. This issue is
fixed in versions 460.32.03 and 450.102.04.

- CVE-2021-1053 (denial of service)

The NVIDIA GPU Display Driver, all versions of the R460 and R450 driver
branches, contains a vulnerability in the kernel mode layer (nvidia.ko)
handler for DxgkDdiEscape or IOCTL in which improper validation of a
user pointer may lead to denial of service. This issue is fixed in
versions 460.32.03 and 450.102.04.

- CVE-2021-1056 (information disclosure)

The NVIDIA GPU Display Driver contains a vulnerability in the kernel
mode layer (nvidia.ko) in which it does not completely honor operating
system file system permissions to provide GPU device-level isolation,
which may lead to denial of service or information disclosure. This
issue is fixed in versions 460.32.03, 450.102.04 and 390.141.

Impact
======

A local user might crash the service, escalate privileges or disclose
sensitive information.
