Affected files ============== The file(s) affected by this issue are: drivers/nfc/fdp/i2c.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/ad11b872bc9b5d27e56183c6b01f9218c85395d2 https://git.kernel.org/stable/c/98f49e693e02c1dafd5786be3468657840dd6f06 https://git.kernel.org/stable/c/0a3664a1058d4b2b1ea2112cc275ca47fba7fc08 https://git.kernel.org/stable/c/80be62358fa5507cefbaa067c7e6648401f2c3da https://git.kernel.org/stable/c/4357bbb921fe9e81d0fd9f70d669d1f177d8380e https://git.kernel.org/stable/c/ce93f1afc05941a572f5a69e2ed4012af905a693 https://git.kernel.org/stable/c/27824b2f98818215adc9661e563252c48dab1a13 https://git.kernel.org/stable/c/11f180a5d62a51b484e9648f9b310e1bd50b1a57
