| Subject: CVE-2022-48686: nvme-tcp: fix UAF when detecting digest errors |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| nvme-tcp: fix UAF when detecting digest errors |
| |
| We should also bail from the io_work loop when we set rd_enabled to true, |
| so we don't attempt to read data from the socket when the TCP stream is |
| already out-of-sync or corrupted. |
| |
| The Linux kernel CVE team has assigned CVE-2022-48686 to this issue. |

| 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: |
