NVIDIA has released a software security update for the NVIDIA GPU Display
Driver R390 linux driver branch. This update addresses issues that may lead to
denial of service, escalation of privileges, information disclosure, data
tampering or undefined behavior.

CVE-2022-34670

NVIDIA GPU Display Driver for Linux contains a vulnerability in the
kernel mode layer handler, where an unprivileged regular user can
cause truncation errors when casting a primitive to a primitive of
smaller size causes data to be lost in the conversion, which may
lead to denial of service or information disclosure.

CVE-2022-34674

NVIDIA GPU Display Driver for Linux contains a vulnerability in the
kernel mode layer handler, where a helper function maps more
physical pages than were requested, which may lead to undefined
behavior or an information leak.

CVE-2022-34675

NVIDIA Display Driver for Linux contains a vulnerability in the
Virtual GPU Manager, where it does not check the return value from a
null-pointer dereference, which may lead to denial of service.

CVE-2022-34677

NVIDIA GPU Display Driver for Linux contains a vulnerability in the
kernel mode layer handler, where an unprivileged regular user can
cause an integer to be truncated, which may lead to denial of
service or data tampering.

CVE-2022-34680

NVIDIA GPU Display Driver for Linux contains a vulnerability in the
kernel mode layer handler, where an integer truncation can lead to
an out-of-bounds read, which may lead to denial of service.

CVE-2022-42257

NVIDIA GPU Display Driver for Linux contains a vulnerability in the
kernel mode layer (nvidia.ko), where an integer overflow may lead to
information disclosure, data tampering or denial of service.

CVE-2022-42258

NVIDIA GPU Display Driver for Linux contains a vulnerability in the
kernel mode layer (nvidia.ko), where an integer overflow may lead to
denial of service, data tampering, or information disclosure.

CVE-2022-42259

NVIDIA GPU Display Driver for Linux contains a vulnerability in the
kernel mode layer (nvidia.ko), where an integer overflow may lead to
denial of service.

For Debian 10 buster, these problems have been fixed in version
