Linux Kernel V4L2 Memory Leak Vulnerability in OV5648 Image Sensor Driver

A memory leak vulnerability has been identified in the Linux kernel's Video4Linux2 (V4L2) subsystem, specifically within the OV5648 image sensor driver. The issue arises because the V4L2 fwnode data structure is not properly freed when the driver is unbound, leading to a memory leak. This vulnerability affects the Linux kernel stable tree.

Impact

The vulnerability causes a memory leak, which can lead to increased memory usage and potential exhaustion of system resources over time.

Remediation

Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit that resolves this issue is available in the Linux kernel stable tree.
