Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/ath6kl/htc_pipe.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/f2a429e6da37e32438a9adc250cc176a889c16a4 https://git.kernel.org/stable/c/e7865f84adaf75cee1a4bbf79680329eca92b4e1 https://git.kernel.org/stable/c/0d1792c98351b7c8ebdc53d052918e77d1e512c3 https://git.kernel.org/stable/c/1300517e371e4d0acdb0f1237477e1ed223c3a9a https://git.kernel.org/stable/c/484d95c69fc1143f09e4c2e3b89019d68d190a92 https://git.kernel.org/stable/c/644df7e865e76ab7a62c67c25cbbc093c944d0ef https://git.kernel.org/stable/c/6f93154d61b345acbc405c6dee16afb845eb298e https://git.kernel.org/stable/c/cbec770521ebc455c9811a23222faf8911422d4a https://git.kernel.org/stable/c/75c4a8154cb6c7239fb55d5550f481f6765fb83c
