Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A reference leak occurs in the Linux kernel when
pm runtime get sync fails. The PM reference count is not expected to be incremented on return in functions cdns i2c master xfer and cdns reg slave. However, pm runtime get sync will increment the pm usage counter even if it fails. Forgetting to put the operation will result in a reference leak. This issue can be resolved by replacing pm runtime get sync with pm runtime resume and get to keep the usage counter balanced.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
