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。- HIDapple驗證功能報告欄位計數以防止 NULL 指標解除參照。具有 quirk APPLE_MAGIC_BACKLIGHT 的惡意 HID 裝置可在切換電源功能報告並將其傳送至 apple_magic_backlight_report_set() 中的裝置時觸發 NULL 指標解除參照。超級功能報告預期有兩個資料欄位但如果描述符號宣告一個欄位則在 apple_magic_backlight_report_set() 中存取欄位[1] 和解除參照欄位會變得無效因為欄位[1] 將為 NULL。可造成當機的最小描述符號範例如下所示其中 ID 為 3 的報告 (power report) 僅參照單一 1 位元組欄位。hid 核心在剖析描述元時會遇到最終功能標籤、配置 hid_report (field[] 的所有成員都會歸零)、建立欄位結構並加以填入進而將 maxfield 增加到 1。隨後的 field[1] 存取權和 解除參照會造成當機。使用量頁面 (供應商定義的 0xFF00) 使用量 (0x0F) 集合 (應用程式) 報告 ID (1) 使用量 (0x01) 最小值邏輯 (0) 邏輯最大值 (255) 報告大小 (8) 報告計數 (1) 功能 (Data、Var、 Abs) 使用量 (0x02) 邏輯最大值 (32767) 報告大小 (16) 報告計數 (1) 功能 (Data,Var,Abs) 報告 ID (3) 使用量 (0x03) 邏輯最小值 (0) 邏輯最大值 (1) 報告大小(8) Report Count (1) Feature (Data,Var,Abs) End Collection 此處我們看到當核心解除參照 NULL 指標並當機時KASAN 展開 [ 15.164723] Oops一般保護錯誤可能是針對非正式位址0xdffffc00000000060000 [#1] SMP KASAN NOPTI [ 15.165691] KASAN 範圍 [0x0000000000000030-0x000000000000037] 中的 null-ptr-deref] [ 15.165691] CPU: 0 UID: 0 PID: 10 Comm: kworker/0:1 未污染 6.15.0 #31 PREEMPT(自發) [ 15.165691] 硬體名稱QEMU Standard PC (i440FX + PIIX, 1996)BIOS 1.16.2-debian-1.16.2-1 04/01/2014 [ 15.165691] RIP 0010:apple_magic_backlight_report_set+ 0xbf/0x210 [15.165691] 呼叫追踪[ 15.165691] <TASK> [ 15.165691] appl e_probe+0x571/0xa20 [ 15.165691] hid_device_probe+0x2e2/0x6f0 [ 15.165691] emerge_probe+0x1ca/0x5c0 [ 15.165691]
