Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/ath11k/dp_rx.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/03ed26935bebf6b6fd8a656490bf3dcc71b72679 https://git.kernel.org/stable/c/3a51e6b4da71fdfa43ec006d6abc020f3e22d14e https://git.kernel.org/stable/c/e3199b3fac65c9f103055390b6fd07c5cffa5961 https://git.kernel.org/stable/c/423762f021825b5e57c3d6f01ff96a9ff19cdcd8 https://git.kernel.org/stable/c/69cede2a5a5f60e3f5602b901b52cb64edd2ea6c https://git.kernel.org/stable/c/3f77c7d605b29df277d77e9ee75d96e7ad145d2d
