In the Linux kernel, the following vulnerability has been resolved:
clk: mediatek: Do a runtime PM get on controllers during probe
mt8183-mfgcfg has a mutual dependency with genpd during the probing
stage, which leads to a deadlock in the following call stack:
CPU0: genpd_lock --> clk_prepare_lock
genpd_power_off_work_fn()
genpd_lock()
generic_pm_domain::power_off()
clk_unprepare()
clk_prepare_lock()
CPU1: clk_prepare_lock --> genpd_lock
clk_register()
__clk_core_init()
clk_prepare_lock()
clk_pm_runtime_get()
genpd_lock()
Do a runtime PM get at the probe function to make sure clk_register()
won't acquire the genpd lock. Instead of only modifying mt8183-mfgcfg,
do this on all mediatek clock controller probings because we don't
believe this would cause any regression.
Verified on MT8183 and MT8192 Chromebooks.Data is provided by the National Vulnerability Database (NVD)
