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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
