| Subject: CVE-2024-27045: drm/amd/display: Fix a potential buffer overflow in 'dp_dsc_clock_en_read()' |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amd/display: Fix a potential buffer overflow in 'dp_dsc_clock_en_read()' |
| |
| Tell snprintf() to store at most 10 bytes in the output buffer |
| instead of 30. |
| |
| Fixes the below: |
| drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_debugfs.c:1508 dp_dsc_clock_en_read() error: snprintf() is printing too much 30 vs 10 |
| |
| The Linux kernel CVE team has assigned CVE-2024-27045 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: |
