CVE-2022-50582

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> regulator: core: Prevent integer underflow<br /> <br /> By using a ratio of delay to poll_enabled_time that is not integer<br /> time_remaining underflows and does not exit the loop as expected.<br /> As delay could be derived from DT and poll_enabled_time is defined<br /> in the driver this can easily happen.<br /> <br /> Use a signed iterator to make sure that the loop exits once<br /> the remaining time is negative.
