| Subject: CVE-2024-27039: clk: hisilicon: hi3559a: Fix an erroneous devm_kfree() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| clk: hisilicon: hi3559a: Fix an erroneous devm_kfree() |
| |
| 'p_clk' is an array allocated just before the for loop for all clk that |
| need to be registered. |
| It is incremented at each loop iteration. |
| |
| If a clk_register() call fails, 'p_clk' may point to something different |
| from what should be freed. |
| |
| The best we can do, is to avoid this wrong release of memory. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27039 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: |
