Affected files ============== The file(s) affected by this issue are: drivers/media/i2c/ov5675.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/086a80b842bcb621d6c4eedad20683f1f674d0c2 https://git.kernel.org/stable/c/bcae9115a163198dce9126aa8bedc1c007ec30ed https://git.kernel.org/stable/c/ba54908ae8225d58f1830edb394d4153bcb7d0aa https://git.kernel.org/stable/c/49b849824b9862f177fc77fc92ef95ec54566ecf https://git.kernel.org/stable/c/7a36a6be694df87d019663863b922913947b42af https://git.kernel.org/stable/c/dd74ed6c213003533e3abf4c204374ef01d86978
