Description

- CVE-2021-1093 (denial of service)

The NVIDIA GPU Display Driver for Windows and Linux contains a
vulnerability in firmware where the driver contains an assert() or
similar statement that can be triggered by an attacker, which leads to
an application exit or other behavior that is more severe than
necessary, and may lead to denial of service or system crash.

- CVE-2021-1094 (information disclosure)

The NVIDIA GPU Display Driver for Windows and Linux contains a
vulnerability in the kernel mode layer handler for DxgkDdiEscape where
an out of bounds array access may lead to denial of service or
information disclosure.

- CVE-2021-1095 (denial of service)

The NVIDIA GPU Display Driver for Windows and Linux contains a
vulnerability in the kernel mode layer handlers for all control calls
with embedded parameters where dereferencing an untrusted pointer may
lead to denial of service.

Impact
======

A local attacker could disclose sensitive memory contents or crash the
system through crafted system calls to the graphics driver.
