Affected files ============== The file(s) affected by this issue are: drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_buffer.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/35b8c0a284983b71d92d082c54b7eb655ed4194f https://git.kernel.org/stable/c/16857370b3a30663515956b3bd27f3def6a2cf06 https://git.kernel.org/stable/c/9ce662851380fe2018e36e15c0bdcb1ad177ed95 https://git.kernel.org/stable/c/dadf9116108315f2eb14c7415c7805f392c476b4 https://git.kernel.org/stable/c/9ddb4cf2192c213e4dba1733bbcdc94cf6d85bf7 https://git.kernel.org/stable/c/8114ef86e2058e2554111b793596f17bee23fa15
