Affected files ============== The file(s) affected by this issue are: drivers/staging/vme_user/vme_fake.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/e831fdd60e5863ee03173baf5a0f7c5450b44381 https://git.kernel.org/stable/c/69b43937f14bdc3594f57f1a507a14f3d1187136 https://git.kernel.org/stable/c/09be0e7ac5f9374b6f8de72c89ed67129af71f65 https://git.kernel.org/stable/c/f3f65c4177846c483bf009f8c512ab04b3c62466 https://git.kernel.org/stable/c/37d3de40c1ffb6a5e626bf46ff5ef5766c824e2c https://git.kernel.org/stable/c/4bc217b25ea81034fad8e33fd33e4659f086421d https://git.kernel.org/stable/c/a2a93546d414c7fe4862b87183fb737d1300d9d2 https://git.kernel.org/stable/c/60ff9bd4ffc87bace581e235a6728f5ac8e5071f https://git.kernel.org/stable/c/7bef797d707f1744f71156b21d41e3b8c946631f
