Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/ar5523/ar5523.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/79ddf5f2020fd593d50f1363bb5131283d74f78f https://git.kernel.org/stable/c/68a5a00c5d38978a3f8460c6f182f7beec8688ff https://git.kernel.org/stable/c/ee25389df80138907bc9dcdf4a2be2067cde9a81 https://git.kernel.org/stable/c/b4c24de37a6bb383394a6fef2b85a6db41d426f5 https://git.kernel.org/stable/c/34f7ebff1b9699e0b89fa58b693bc098c2f5ec72 https://git.kernel.org/stable/c/b33a81e4ecfb022b028cae37d1c1ce28ac1b359d https://git.kernel.org/stable/c/beeed260b92af158592f5e8d2dab65dae45c6f70 https://git.kernel.org/stable/c/7bbf76c9bb2c58375e183074e44f9712483f0603 https://git.kernel.org/stable/c/e120b6388d7d88635d67dcae6483f39c37111850
