In the Linux kernel, the following vulnerability has been resolved:pmdomain: mediatek: fix race conditions with genpdIf the power domains are registered first with genpd and *after that*the driver attempts to power them on in the probe sequence, then it ispossible that a race condition occurs if genpd tries to power them onin the same time.The same is valid for powering them off before unregistering themfrom genpd.Attempt to fix race conditions by first removing the domains from genpdand *after that* powering down domains.Also first power up the domains and *after that* register themto genpd.
