Description

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dsi: Drop dev_pm_opp_set_rate(0) dev_pm_opp_set_rate(0) removes the vote specified in required-opps but does not actually park the clock, making it run without the necessary power backing. Drop the explicit call to it. Every call site of ops->link_clk_disable() is followed by pm_runtime_put(), so the power vote will be rescinded if deemed safe. Patchwork: https://patchwork.freedesktop.org/patch/742783/

Affected products

• Linux kernel: 5.9 — fixed in 7.3

How to fix

Upgrade to a fixed version: Linux kernel 7.3. Check the vendor advisory for mitigations.
