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