CVE-2026-46239 Details
Description
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.
A runtime reference count leak vulnerability has been identified in the Linux kernel's OV5647 I2C driver. This issue arises because the driver improperly handles three control cases—AUTOGAIN, EXPOSURE_AUTO, and ANALOGUE_GAIN—by directly returning values without first calling 'pm_runtime_put()'. This oversight leads to a leak in the runtime power management reference count. The vulnerability affects the stable versions of the Linux kernel.
Users can apply the latest patch available in the Linux kernel stable tree to address this vulnerability. The patch can be downloaded from the Linux kernel Git repository.
