| Subject: CVE-2024-57887: drm: adv7511: Fix use-after-free in adv7533_attach_dsi() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm: adv7511: Fix use-after-free in adv7533_attach_dsi() |
| |
| The host_node pointer was assigned and freed in adv7533_parse_dt(), and |
| later, adv7533_attach_dsi() uses the same. Fix this use-after-free issue |
| by dropping of_node_put() in adv7533_parse_dt() and calling of_node_put() |
| in error path of probe() and also in the remove(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-57887 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: |
