Affected files ============== The file(s) affected by this issue are: drivers/staging/rtl8723bs/core/rtw_ieee80211.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/ac38856092b4c994f94343251b30520bdeb7f475 https://git.kernel.org/stable/c/35969c3a208a07cb8642301df5869c34e2db7071 https://git.kernel.org/stable/c/8097a48c606a9306281ea7bd73bf2afc97553733 https://git.kernel.org/stable/c/740bca8bbdb707c0e4bb11e3316deb2f04fc7ce1 https://git.kernel.org/stable/c/821f7d759fb2de33c5e5b0c4981181c4d0c3e9b1 https://git.kernel.org/stable/c/6d62fa548387e159a21ea95132c09bfc96d336ed https://git.kernel.org/stable/c/9a4cd4c37593cc8b8d28f9a6732b490a8032006a https://git.kernel.org/stable/c/f0109b9d3e1e455429279d602f6276e34689750a
