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

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.

The check returns affected, not affected, or incomplete. It does not guess a version that is missing from the record.

What to do

Three questions, each answered from this record only. Confirm the vendor advisory before you patch.

Should you patch?

Exploitation likelihood is not on this record for CVE-2022-50582. A missing EPSS score is not a low risk. Compare Linux Linux with the linked advisory before you change production.

Which versions are affected?

Compare what you have installed with Linux Linux f7d7ad42a9dc2d63cab6a79fe31e6732a30dacf5 <9f2395316e4845466cb9b5b9b15a171a2c91913c f7d7ad42a9dc2d63cab6a79fe31e6732a30dacf5 <9f2395316e4845466cb9b5b9b15a171a2c91913c. Compare the installed version with the linked vendor advisory before you change production.

What should an analyst verify?

No weakness class is stored. EPSS is absent from the current FIRST dataset. There is no CISA KEV listing. No Exploit-DB or Metasploit reference is linked. Use the source links for the original advisory.
