| Subject: CVE-2024-53080: drm/panthor: Lock XArray when getting entries for the VM |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drm/panthor: Lock XArray when getting entries for the VM |
| |
| Similar to commit cac075706f29 ("drm/panthor: Fix race when converting |
| group handle to group object") we need to use the XArray's internal |
| locking when retrieving a vm pointer from there. |
| |
| v2: Removed part of the patch that was trying to protect fetching |
| the heap pointer from XArray, as that operation is protected by |
| the @pool->lock. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53080 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: |
