| Subject: CVE-2023-52691: drm/amd/pm: fix a double-free in si_dpm_init |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amd/pm: fix a double-free in si_dpm_init |
| |
| When the allocation of |
| adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, |
| amdgpu_free_extended_power_table is called to free some fields of adev. |
| However, when the control flow returns to si_dpm_sw_init, it goes to |
| label dpm_failed and calls si_dpm_fini, which calls |
| amdgpu_free_extended_power_table again and free those fields again. Thus |
| a double-free is triggered. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52691 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: |
