Title
leds: qcom-lpg: Check for array overflow when selecting the high resolution
Summary
In the Linux kernel, the following vulnerability has been resolved: leds: qcom-lpg: Check for array overflow when selecting the high resolution When selecting the high resolution values from the array, FIELD_GET() is used to pull from a 3 bit register, yet the array being indexed has only 5 values in it. Odds are the hardware is sane, but just to be safe, properly check before just overflowing and reading random data and then setting up chip values based on that.
Severity
