Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/ath11k/spectral.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/60afa4f4e1350c876d8a061182a70c224de275dd https://git.kernel.org/stable/c/451b9076903a057b7b8d5b24dc84b3e436a1c743 https://git.kernel.org/stable/c/4b9c54caef58d2b55074710952cda70540722c01 https://git.kernel.org/stable/c/8f15e67af9bec5a69e815e0230a70cffddae371a https://git.kernel.org/stable/c/161c64de239c7018e0295e7e0520a19f00aa32dc
