Affected files ============== The file(s) affected by this issue are: drivers/nvme/target/loop.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/9c980795ccd77e8abec33dd6fe28dfe1c4083e65 https://git.kernel.org/stable/c/551ba08d4b7eb26f75758cdb9f15105b276517ad https://git.kernel.org/stable/c/03504e3b54cc8118cc26c064e60a0b00c2308708
