一、漏洞信息
漏洞编号：CVE-2020-36783
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0
CVSS V2.0分值：
BaseScore：0.0 Low
Vector：CVSS：2.0/
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:i2c: img-scb: fix reference leak when pm_runtime_get_sync failsThe PM reference count is not expected to be incremented onreturn in functions img_i2c_xfer and img_i2c_init.However, pm_runtime_get_sync will increment the PM referencecount even failed. Forgetting to putting operation will resultin a reference leak here.Replace it with pm_runtime_resume_and_get to keep usagecounter balanced.

CVE-2020-36783

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

i2c: img-scb: fix reference leak when pm_runtime_get_sync fails

The PM reference count is not expected to be incremented on
return in functions img_i2c_xfer and img_i2c_init.

However, pm_runtime_get_sync will increment the 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.
