阿里云漏洞库

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.
