Background
The soc/tegra: regulators package is a component of the Linux Kernel ecosystem. It is responsible for managing voltage regulators on Tegra-based systems. These voltage regulators control the power supply to various components of the system. The package ensures that the voltage levels are within the acceptable range to prevent damage to the hardware. However, a vulnerability has been discovered in this package that can cause the system to lock up when the voltage-spread is out of range.
Vulnerability Detail
The vulnerability in soc/tegra: regulators arises when the voltage-spread exceeds the acceptable range. This can lead to a system lock-up, rendering the device unresponsive. An attacker could potentially exploit this vulnerability by manipulating the voltage-spread, causing a denial of service (DoS) condition. The vulnerability was introduced in version v5.5 of the Linux Kernel and was fixed in version v5.10.37. The impact and attack plausibility of this vulnerability have not been proven yet.
