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/1e7433fb95ccc01629a5edaa4ced0cd8c98d0ae0 https://git.kernel.org/stable/c/9921c866dc369577c3ebb9adf2383b01b58c18de https://git.kernel.org/stable/c/2526d4d8b209dc5ac1fbeb468149774888b2a141 https://git.kernel.org/stable/c/a9c10b5b3b67b3750a10c8b089b2e05f5e176e33 References: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2022-48773 https://git.kernel.org/pub/scm/linux/security/vulns.git/plain/cve/published/2022/CVE-2022-48773.mbox https://git.kernel.org/stable/c/1e7433fb95ccc01629a5edaa4ced0cd8c98d0ae0 https://git.kernel.org/stable/c/9921c866dc369577c3ebb9adf2383b01b58c18de https://git.kernel.org/stable/c/2526d4d8b209dc5ac1fbeb468149774888b2a141 https://git.kernel.org/stable/c/a9c10b5b3b67b3750a10c8b089b2e05f5e176e33
