| Subject: CVE-2024-43871: devres: Fix memory leakage caused by driver API devm_free_percpu() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| devres: Fix memory leakage caused by driver API devm_free_percpu() |
| |
| It will cause memory leakage when use driver API devm_free_percpu() |
| to free memory allocated by devm_alloc_percpu(), fixed by using |
| devres_release() instead of devres_destroy() within devm_free_percpu(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-43871 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: |
