Background

The soc/tegra: regulators is a component in the Linux Kernel that handles voltage regulation for Tegra SoCs. It ensures that the voltage supplied to different components of the system remains within the specified range. However, a vulnerability has been discovered in this component 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 the system becoming unresponsive or freezing. An attacker could potentially exploit this vulnerability to cause a denial of service (DoS) by deliberately manipulating the voltage-spread. The vulnerability was introduced in Linux Kernel version v5.5 and has been fixed in version v5.12.4.

How To Fix

No fixed version is published for this vulnerability.

There is no specific workaround mentioned for this vulnerability.

Conclusion

The soc/tegra: regulators component in the Linux Kernel is vulnerable to a DoS condition when the voltage-spread is out of range. It is recommended to update the Linux Kernel to version v5.12.4 or later to mitigate this vulnerability. For further support on vulnerability remediation, you can contact DevNack.com.
