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，且供應商未提供可用的修補程式。- cifs修正 refresh_cache_worker() 中的釋放後使用錯誤。發生 UAF 錯誤的原因是我們在執行 DFS 快取重新整理時將 DFS root 工作階段置於 cifs_umount() 中。使 DFS root 工作階段具有與 DFS tcon 相同的存留期因此我們可以避免在 DFS 快取重新整理及其他需要 IPC 以取得新 DFS 轉介的位置的釋放後使用錯誤。此外我們也捨棄 DFS 快取中的掛載群組處理因為我們不再需要它。這可修正 KASAN 擷取的下列釋放後使用錯誤 [ 379.946955] 錯誤KASAN在 __refresh_tcon.isra.0+0x10b/0xc10 中釋放後使用 [cifs] [ 379.947642] 於 addr ffff888018f57030 讀取大小為 8 的錯誤task kworker/u4:3/56 [ 379.948096] [ 379.948208] CPU: 0 PID: 56 Comm: kworker/u4:3 未受污染的 6.2.0-rc7-lku #23 [ 379.948661] 硬體名稱: QEMU Standard PC (Q35 + ICH9, 2009)BIOS rel-1.16.0-0-gd239552-rebuilt.opensuse.org 04/01/2014 [ 379.949368] Workqueuecifs-dfscache refresh_cache_worker [cifs] [ 379.949942] 呼叫追踪[ 379.950113] <TASK> [ 379.950260] dump_stack_lvl+0x50/0x67 [ 379.950510] print_report+0x16a/0x48e [ 379.950759] ?
