In recent times, Nvidia acknowledged three security bugs in the Nvidia Shield TV which could have proved to be harmful and may permit services denial with rights escalation and data loss of the user. Nvidia Shield TV has been developed for gamers to play smart house, PC games from the PC console to television, and stream on and off the local and online internet servers. Better said, it’s a “set-top gadget” used for gaming. Subsequently, for the video-friendly graphics processing unit (GPU) monitor device, Nvidia solely published a security alert for a security bug cluster detected.
Nvidia Shield TV interface, the NVDEC part of the hardware-dependent decoder encompasses a high– severity by CVE- 2021- 1068. Such bugs arise in the hardware when the actors can write or read from a memory location that is outside the scope of the intended boundary of the buffer. This issue later may lead to a service denial or the escalation of privileges. It has a fair rating of 7.8 CVSS.
The remaining two bugs do not hold high- severity. The flaw CVE- 2021- 1069 was detected in the NV host feature and could easily cause the data to be lost due to the null point reference. Whereas another bug CVE- 2021- 1067 endures in the application of the RPMB command status. In the RPMB command, the actors can write to the Write Protect Configuration Block, which also may lead to a service denial or the escalation of privileges. By using the upgrade note that appears on the notification screen, or via the Settings>About>System update, users can download and install the software update to secure a system. It will prevent them from any further loss of data by the detected bugs.
