Vulnerability from github – Published: 2024-02-28 09:30 – Updated: 2024-12-06 18:30

Details

In the Linux kernel, the following vulnerability has been resolved:

i2c: xiic: fix reference leak when pm_runtime_get_sync fails

The PM reference count is not expected to be incremented on return in xiic_xfer and xiic_i2c_remove.

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.

Severity ?

5.5 (Medium)
