However, this is not always the case. Fix this by passing the desired offset and length to be_cmd_read_port_transceiver_data so that we only copy the bytes once. The Linux kernel CVE team has assigned CVE-2022-49581 to this issue.

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/a5a8fc0679a8fd58d47aa2ebcfc5742631f753f9 https://git.kernel.org/stable/c/fe4473fc7940f14c4a12db873b9729134c212654 https://git.kernel.org/stable/c/8ff4f9df73e5c551a72ee6034886c17e8de6596d https://git.kernel.org/stable/c/a8569f76df7ec5b4b51155c57523a0b356db5741 https://git.kernel.org/stable/c/665cbe91de2f7c97c51ca8fce39aae26477c1948 https://git.kernel.org/stable/c/aba8ff847f4f927ad7a1a1ee4a9f29989a1a728f https://git.kernel.org/stable/c/18043da94c023f3ef09c15017bdb04e8f695ef10 https://git.kernel.org/stable/c/d7241f679a59cfe27f92cb5c6272cb429fb1f7ec
