Affected files ============== The file(s) affected by this issue are: drivers/video/fbdev/metronomefb.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/77e26383083c59a67244fcf2e70eecd354451906 https://git.kernel.org/stable/c/f779bd494f9521f89bfd4ce23953f3527341e9fd https://git.kernel.org/stable/c/01708cf3dca2f88eca26269521cbcc8e2f054ee4 https://git.kernel.org/stable/c/d54bb39cd34f44b32d5c4a8416fff8b01a9e76be https://git.kernel.org/stable/c/6854cf33dddb212bd7c3d69189623876e7334075 https://git.kernel.org/stable/c/a889978ec44fe33edb3fb7140dcbbb8e6465c1cb https://git.kernel.org/stable/c/894632b862a39b3fe1cb5de06fbae86225ea64de
