Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/ath9k/htc_hst.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/db8df00cd6d801b3abdb145201c2bdd1c665f585 https://git.kernel.org/stable/c/9e3031eea2d45918dc44cbfc6a6029e82882916f https://git.kernel.org/stable/c/4dc3560561a08842b4a4c07ccc5a90e5067dbb5b https://git.kernel.org/stable/c/1044187e7249073f719ebbf9e5ffb4f16f99e555 https://git.kernel.org/stable/c/95b4b940f0fb2873dcedad81699e869eb7581c85 https://git.kernel.org/stable/c/09740fa9827cfbaf23ecd041e602a426f99be888 https://git.kernel.org/stable/c/6a444dffb75238c47d2d852f12cf53f12ad2cba8 https://git.kernel.org/stable/c/be2a546c30fe8d72efa032bee612363bb75314bd https://git.kernel.org/stable/c/061b0cb9327b80d7a0f63a33e7c3e2a91a71f142
