| Subject: CVE-2024-26649: drm/amdgpu: Fix the null pointer when load rlc firmware |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/amdgpu: Fix the null pointer when load rlc firmware |
| |
| If the RLC firmware is invalid because of wrong header size, |
| the pointer to the rlc firmware is released in function |
| amdgpu_ucode_request. There will be a null pointer error |
| in subsequent use. So skip validation to fix it. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26649 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: |
| https://git.kernel.org/stable/c/8b5bacce2d13dbe648f0bfd3f738ecce8db4978c |
