CVE-2026-46239

Power-management disruption via leaked runtime references

Published May 28, 2026 · Updated May 28, 2026

Resource leak in the Linux Kernel ov5647 driver 7.0 through 7.0.8 allows local users to keep the camera device active via control changes. The ov5647_s_ctrl function returns from three control cases without calling pm_runtime_put, leaking a reference acquired by pm_runtime_resume_and_get. An ov5647 device and local access to issue AUTOGAIN, EXPOSURE_AUTO, or ANALOGUE_GAIN controls are required; no data access or code execution is reported.
