Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/rsi/rsi_91x_coex.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/98259e0b6cf7f021da9fe4e11fbcce6ad6705ffe https://git.kernel.org/stable/c/fe4d7280cf4ddbea6536b596297c07662c7856fc https://git.kernel.org/stable/c/efc8df970561ff708379b89b348e16d3b410cc7b https://git.kernel.org/stable/c/b56e60b3b158a93bc713437e8e466f401ff8cc9f https://git.kernel.org/stable/c/c4f1ded67a90fb3b2e679e2c90b78921d9246044 https://git.kernel.org/stable/c/ace789b1d465fae104cd37e49f6e1bcd1c8ff417 https://git.kernel.org/stable/c/956fb851a6e19da5ab491e19c1bc323bb2c2cf6f
