Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： drm/msm/dsi：移除 dev_pm_opp_set_rate(0) 虽然会移除在 中指定的投票（vote），但并不会真正让时钟进入省电（park）状态，导致时钟在无必要功耗支撑的情况下继续运行。因此，应移除对该函数的显式调用。 每个 的调用点之后都会跟随一个 ，因此如果系统认为安全，功耗投票将被撤销。 补丁详情参见：https://patchwork.freedesktop.org/patch/742783/

Vulnerability Title
drm/msm/dsi: Drop dev_pm_opp_set_rate(0)
Source: CVE Program / CVE List V5
Vulnerability 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link_clk_disable() is followed by pm_runtime_put(), so the power vote will be rescinded if deemed safe.
