Nvidia Squashes High-Severity Jetson DoS Flaw

  • If exploited, the most critical of these flaws could lead to a denial-of-provider issue for Jetson products and solutions.

    Nvidia has patched 3 vulnerabilities influencing its Jetson lineup, which is a series of embedded computing boards built for device-learning programs, in matters like autonomous robots, drones and more. A effective exploit could most likely cripple any such gadgets leveraging the afflicted Jetson products and solutions, stated Nvidia.

    If exploited, the most severe of these flaws could direct to a denial-of-service (DoS) condition for afflicted items. The flaw (CVE-2021-1070) ranks 7.1 out of 10 on the CVSS scale, creating it higher-severity. It particularly exists in the Nvidia Linux Driver Offer (L4T), the board aid deal for Jetson solutions.

    Nvidia L4T contains a glitch in the utilize_binaries.sh script. This script is applied to set up Nvidia elements into the root file process impression. The script allows incorrect access manage, which might guide to an unprivileged user getting in a position to modify program device tree information. System trees are a facts construction of the components parts of a unique laptop, which make it possible for an running system’s kernel to use and handle all those parts, which include the CPU, memory, and peripherals.

    Accessibility to a machine tree file could make it possible for an attacker to start a DoS attack. Further particulars about the flaw – which includes what an attacker requirements to exploit it – were not disclosed. The issue was identified by programmer Michael de Gans.

    All versions prior to L4T release r32.5 are afflicted a patch is obtainable in L4T launch r32.5. Particular Jetson products influenced consist of the Jetson TX1 and TX2 sequence which are two lower-ability embedded computing boards that have a Nvidia Tegra processor and are precisely designed for accelerating device learning in techniques. Also impacted are the Jetson AGX Xavier sequence, a developer package that is primarily an synthetic intelligence pc for autonomous machines the Jetson Xavier NX developer kit and the Jetson Nano and Jetson Nano 2GB developer kits.

    The other two are medium-severity flaws (CVE‑2021‑1069 and CVE‑2021‑1071), which ended up uncovered in the Nvidia Tegra’s kernel driver. This is code that allows the kernel to communicate to the components gadgets that the procedure-on-a-chip (SoC) is in.

    CVE‑2021‑1069 exists in NVHost, a software host that is portion of Nvidia Driver Helper Assistance. NVHost will allow a variable to be null, which may possibly guide to a null pointer dereference and unpredicted reboot, eventually leading to knowledge decline, according to Nvidia.

    CVE‑2021‑1071 in the meantime exists in the INA3221 driver, an on-board electrical power keep track of that screens the voltage and present-day of sure rails. The flaw enables incorrect entry control, which may well direct to unauthorized end users getting entry to technique electrical power utilization information. This can guide to information and facts disclosure.

    It’s only the newest set of patches to be launched by Nvidia this month. Very last week, Nvidia recently disclosed 3 security vulnerabilities in the NVIDIA Shield Television, which could permit denial of company, escalation of privileges and information loss. Before in January, Nvidia patched flaws tied to 16 CVEs across its graphics drivers and vGPU software, in its first security update of 2021. An up-to-date security advisory now incorporates the availability of patched Linux drivers for the Tesla line of GPUs, influencing CVE-2021-1052, CVE-2021-1053 and CVE-2021-1056.
