Description
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: clk-rcg2: Update logic to calculate D value for RCG
The display pixel clock has a requirement on certain newer platforms to
support M/N as (2/3) and the final D value calculated results in
underflow errors.
As the current implementation does not check for D value is within
the accepted range for a given M & N value. Update the logic to
calculate the final D value based on the range.
Affected configurations
• linux linux kernel (>= 3.16 < 5.4.189)
• linux linux kernel (>= 5.5 < 5.10.110)
• linux linux kernel (>= 5.11 < 5.15.33)
• linux linux kernel (>= 5.16 < 5.16.19)
• linux linux kernel (>= 5.17 < 5.17.2)
