This can result in a segfault if the error condition is hit, and we try to access i2c_client, so fix the order. The Linux kernel CVE team has assigned CVE-2026-43312 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/media/i2c/ov5647.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/f2a1998bc0053ebfe137f65081ed13afd9f34502 https://git.kernel.org/stable/c/59e372aa4cf60e2500eba7f978acdcb18bb49032 https://git.kernel.org/stable/c/cabd025182cfed4a19b3aab57493e312d681e398 https://git.kernel.org/stable/c/2dedda97a64e7735844609c6c77c0dd953d73833 https://git.kernel.org/stable/c/8ecb21c20387cc0c8aa00489a21ccc69f6b0f5d1 https://git.kernel.org/stable/c/fb69e4842f5b463ff5f121d2ac7746014e3477ea https://git.kernel.org/stable/c/eee13cbccacb6d0a3120c126b8544030905b069d
