Doc Text:
A flaw was found in the Linux kernel's ov8856 media driver. This vulnerability occurs due to improper error handling where a control handler is not correctly released if an error occurs during its initialization. This oversight could potentially lead to resource exhaustion, which may result in a denial of service (DoS) condition, making the system unavailable to legitimate users.

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

exit label and convert the existing error return to use it.
