| Subject: CVE-2024-26585: tls: fix race between tx work scheduling and socket close |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| tls: fix race between tx work scheduling and socket close |
| |
| Similarly to previous commit, the submitting thread (recvmsg/sendmsg) |
| may exit as soon as the async crypto handler calls complete(). |
| Reorder scheduling the work before calling complete(). |
| This seems more logical in the first place, as it's |
| the inverse order of what the submitting thread will do. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26585 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: |
