free control handler on error in ov8856_init_controls
Summary
In the Linux kernel, the following vulnerability has been resolved: media: i2c: ov8856: free control handler on error in ov8856_init_controls() The control handler wasn't freed if adding controls failed, add an error exit label and convert the existing error return to use it. 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. Red Hat severity: Low — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-772.
