Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: i2c: imx: fix reference leak when pm_runtime_get_sync fails In i2c_imx_xfer() and i2c_imx_remove(), the pm reference count is not expected to be incremented on return. However, pm_runtime_get_sync will increment pm reference count even failed. Forgetting to putting operation will result in a reference leak here. Replace it with pm_runtime_resume_and_get to keep usage counter balanced.
