CVE-2024-50266
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: videocc-sm8350: use HW_CTRL_TRIGGER for vcodec GDSCs
A recent change in the venus driver results in a stuck clock on the Lenovo ThinkPad X13s, for example, when streaming video in firefox:
using the out-of-tree sm8350/sc8280xp venus support. [1]
Update also the sm8350/sc8280xp GDSC definitions so that the hw control mode can be changed at runtime as the venus driver now requires.
