| Subject: CVE-2024-42309: drm/gma500: fix null pointer dereference in psb_intel_lvds_get_modes |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/gma500: fix null pointer dereference in psb_intel_lvds_get_modes |
| |
| In psb_intel_lvds_get_modes(), the return value of drm_mode_duplicate() is |
| assigned to mode, which will lead to a possible NULL pointer dereference |
| on failure of drm_mode_duplicate(). Add a check to avoid npd. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42309 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: |
