Background
The Kernel package is a crucial component of the Linux operating system, responsible for managing the system's core functionality. One of its subcomponents, clk-rcg2, handles the calculation of the D value for RCG (Rate Change Gear) operations. RCG is a clock framework used in Qualcomm processors. This vulnerability affects versions of the Linux Kernel from v3.16 to v5.17.1.
Vulnerability Detail
The vulnerability in clk-rcg2 arises from a flaw in the logic used to calculate the D value for RCG. An attacker could potentially exploit this vulnerability to manipulate clock settings and disrupt the normal operation of the system. The impact and attack plausibility of this vulnerability have not been proven yet.
How To Fix
No fixed version is published for this vulnerability.
To address this vulnerability, it is recommended to update the Linux Kernel package to version v5.17.2 or later. This update includes a fix for the flawed logic in clk-rcg2. Users can obtain the updated package from the official Linux Kernel repository.
