| Subject: CVE-2024-38547: media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries |
| |
| The allocation failure of mycs->yuv_scaler_binary in load_video_binaries() |
| is followed with a dereference of mycs->yuv_scaler_binary after the |
| following call chain: |
| |
| sh_css_pipe_load_binaries() |
| |-> load_video_binaries(mycs->yuv_scaler_binary == NULL) |
| | |
| |-> sh_css_pipe_unload_binaries() |
| |-> unload_video_binaries() |
| |
| In unload_video_binaries(), it calls to ia_css_binary_unload with argument |
| &pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the |
| same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer |
| dereference is triggered. |
| |
| The Linux kernel CVE team has assigned CVE-2024-38547 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: |
