Affected files ============== The file(s) affected by this issue are: drivers/staging/r8188eu/os_dep/ioctl_linux.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/ac2eab7de458f5e1210ce1237afab40a307075c8 https://git.kernel.org/stable/c/c4bd6b72df4f01aa866ceb298466d6d07a6bd525 https://git.kernel.org/stable/c/476bfda0be0f9669add92bff604ca78226cf53d1 https://git.kernel.org/stable/c/bc10916e890948d8927a5c8c40fb5dc44be5e1b8
