| Subject: CVE-2024-58052: drm/amdgpu: Fix potential NULL pointer dereference in atomctrl_get_smc_sclk_range_table |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amdgpu: Fix potential NULL pointer dereference in atomctrl_get_smc_sclk_range_table |
| |
| The function atomctrl_get_smc_sclk_range_table() does not check the return |
| value of smu_atom_get_data_table(). If smu_atom_get_data_table() fails to |
| retrieve SMU_Info table, it returns NULL which is later dereferenced. |
| |
| Found by Linux Verification Center (linuxtesting.org) with SVACE. |
| |
| In practice this should never happen as this code only gets called |
| on polaris chips and the vbios data table will always be present on |
| those chips. |
| |
| The Linux kernel CVE team has assigned CVE-2024-58052 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: |
