| Subject: CVE-2024-39493: crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak |
| |
| Using completion_done to determine whether the caller has gone |
| away only works after a complete call. Furthermore it's still |
| possible that the caller has not yet called wait_for_completion, |
| resulting in another potential UAF. |
| |
| Fix this by making the caller use cancel_work_sync and then freeing |
| the memory safely. |
| |
| The Linux kernel CVE team has assigned CVE-2024-39493 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: |
