Affected files ============== The file(s) affected by this issue are: drivers/tty/serial/jsm/jsm_driver.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/ff9a5e50fb1910be33e62925bc7ee3bef474879e https://git.kernel.org/stable/c/3bf05c2650cf6b8d83bf0b0d808cc78c6ee7e84c https://git.kernel.org/stable/c/6066bd69ffba3a6abc7c0793ccba1da79b7d77e3 https://git.kernel.org/stable/c/744c2d33a88b082d9d504520f0132b3d688547b2 https://git.kernel.org/stable/c/71ffe5111f0ffa2fd43c14fd176c6f05d4e82212 https://git.kernel.org/stable/c/6be8e565a4a60530797a974d0a3d0e30656166a1 https://git.kernel.org/stable/c/737594536dc3ce732976c0d84bb1dcc842065521 https://git.kernel.org/stable/c/3ea1fd63fdf0e83b491c2a9f25b395aa0e4bf6e8 https://git.kernel.org/stable/c/1d5859ef229e381f4db38dce8ed58e4bf862006b
