Affected files ============== The file(s) affected by this issue are: drivers/mtd/maps/pxa2xx-flash.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/cb3f35f44887a8486737fe88d58050f1df290758 https://git.kernel.org/stable/c/e2324a0912ad26a0ea5baaf81aed0ca880804158 https://git.kernel.org/stable/c/6fa9550ef3e13d7e9b2d4db6dd57292ccd072a90 https://git.kernel.org/stable/c/cf9c4c25caad05c6b492cbba739a467511814279 https://git.kernel.org/stable/c/1d0c2b762dad2b8dd166e17c0e90b88b86a3284f https://git.kernel.org/stable/c/f35981083cb3fc1ba6427c1543152c5e3f59d104 https://git.kernel.org/stable/c/932baf593eb63dff40e40d7674f076fb7932cd5b https://git.kernel.org/stable/c/a1b061cafdbcb1ff259731f30e2bdc1de64dcaba https://git.kernel.org/stable/c/2399401feee27c639addc5b7e6ba519d3ca341bf
