Affected files ============== The file(s) affected by this issue are: net/bluetooth/hci_core.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/219960a48771b35a3857a491b955c31d6c33d581 https://git.kernel.org/stable/c/559b1c7ac2e212a23b3833d3baf3bd957771d02e https://git.kernel.org/stable/c/5e50d12cc6e95e1fde08f5db6992b616f714b0fb https://git.kernel.org/stable/c/93a6160dc198ffe5786da8bd8588cfd17f53b29a https://git.kernel.org/stable/c/3fe288a8214e7dd784d1f9b7c9e448244d316b47
