Vulnerability from github – Published: 2026-05-28 12:30 – Updated: 2026-05-28 12:30

Details

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

media: i2c: ov5647: Fix runtime PM refcount leak in s_ctrl

Three control cases (AUTOGAIN, EXPOSURE_AUTO, ANALOGUE_GAIN) directly return without calling pm_runtime_put(), causing runtime PM reference count leaks.

Change these cases from 'return' to 'ret = ... break' pattern to ensure pm_runtime_put() is always called before function exit.
