| Subject: CVE-2024-42069: net: mana: Fix possible double free in error handling path |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: mana: Fix possible double free in error handling path |
| |
| When auxiliary_device_add() returns error and then calls |
| auxiliary_device_uninit(), callback function adev_release |
| calls kfree(madev). We shouldn't call kfree(madev) again |
| in the error handling path. Set 'madev' to NULL. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42069 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: |
