NVIDIA GPU and Tegra hardware contain a vulnerability in the internal microcontroller, which may allow a user with elevated privileges to instantiate a DMA write operation only within a specific time window timed to corrupt code execution, which may impact confidentiality, integrity, or availability. The scope impact may extend to other components.

CVE-2021-23201
NVIDIA GPU and Tegra hardware contain a vulnerability in an internal microcontroller, which may allow a user with elevated privileges to generate valid microcode by identifying, exploiting, and loading vulnerable microcode. Such an attack could lead to information disclosure, data corruption, or denial of service of the device. The scope may extend to other components.
CVE-2021-23175
NVIDIA GeForce Experience contains a vulnerability in user authorization, where GameStream does not correctly apply individual user access controls for users on the same device, which, with user intervention, may lead to escalation of privileges, information disclosure, data tampering, and denial of service, affecting other resources beyond the intended security authority of GameStream.
CVE-2021-1109
NVIDIA camera firmware contains a multistep, timing-related vulnerability where an unauthorized modification by camera resources may result in loss of data integrity or denial of service across several streams.
CVE-2021-1105
NVIDIA GPU and Tegra hardware contain a vulnerability in the internal microcontroller which may allow a user with elevated privileges to access debug registers during runtime, which may lead to information disclosure.
CVE-2021-1106
NVIDIA Linux kernel distributions contain a vulnerability in nvmap, where writes may be allowed to read-only buffers, which may result in escalation of privileges, complete denial of service, unconstrained information disclosure, and serious data tampering of all processes on the system.
