Affected files ============== The file(s) affected by this issue are: net/rose/af_rose.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/667f61b3498df751c8b3f0be1637e7226cbe3ed0 https://git.kernel.org/stable/c/e0384efd45f615603e6869205b72040c209e69cc https://git.kernel.org/stable/c/970cd2ed26cdab2b0f15b6d90d7eaa36538244a5 https://git.kernel.org/stable/c/4c04b0ab3a647e76d0e752b013de8e404abafc63 https://git.kernel.org/stable/c/a1300691aed9ee852b0a9192e29e2bdc2411a7e6
