| Subject: CVE-2024-27044: drm/amd/display: Fix potential NULL pointer dereferences in 'dcn10_set_output_transfer_func()' |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amd/display: Fix potential NULL pointer dereferences in 'dcn10_set_output_transfer_func()' |
| |
| The 'stream' pointer is used in dcn10_set_output_transfer_func() before |
| the check if 'stream' is NULL. |
| |
| Fixes the below: |
| drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn10/dcn10_hwseq.c:1892 dcn10_set_output_transfer_func() warn: variable dereferenced before check 'stream' (see line 1875) |
| |
| The Linux kernel CVE team has assigned CVE-2024-27044 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: |
