CVE-2026-46239
Description
A flaw was found in the Linux kernel's media: i2c: ov5647 driver. This issue occurs because certain control cases (AUTOGAIN, EXPOSURE_AUTO, ANALOGUE_GAIN) do not properly release power management (PM) runtime reference counts. This oversight can lead to a resource leak, potentially resulting in a Denial of Service (DoS) due to resource exhaustion.
