Linux Distros 未修補的弱點：CVE-2025-38603
high Nessus Plugin ID 260166
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。- drm/amdgpu修正 amdgpu_userq_mgr_fini+0x70c 中的 slab 釋放後使用。問題是於 NV10 使用 IGT pci_unplug 測試重現。預期在呼叫「amdgpu_drm_release()」之前會先呼叫「amdgpu_driver_postclose_kms()」。不過錯誤在於 `amdgpu_driver_postclose_kms()` 中的 `amdgpu_fpriv` 已釋放之後又透過 `amdgpu_userq_mgr_fini()` 呼叫在 `amdgpu_drm_release()` 中存取。因此KASAN 會偵測到釋放後使用情形，如下面的記錄所示。建議的修正是將 `amdgpu_eviction_fence_destroy()` 與 `amdgpu_userq_mgr_fini()` 的呼叫移至 `amdgpu_driver_postclose_kms()`以便在釋放 `amdgpu_fpriv` 之前叫用它們。這也可確保 `amdgpu_driver_open_kms()` 中初始化路徑的對稱性在該路徑中初始化下列元件- `amdgpu_userq_mgr_init()` - `amdgpu_eviction_fence_init()` - `amdgpu_ctx_mgr_init()` 對應地在 `amdgpu_driver_postclose_kms()`使用以下項目進行清理- `amdgpu_userq_mgr_fini()` - `amdgpu_eviction_fence_destroy()` - `amdgpu_ctx_mgr_fini()`此變更可消除釋放後使用並改善資源管理中開啟和關閉路徑之間的一致性。 [ +0.094367] ============================================= ===================== [ +0.000026] 錯誤
