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。- drm/vgem-fence修正釋放時可能發生的鎖死。現在會在上次 dma_fence_put() 中使用 fence->ops.release() 的 timer_delete_sync() 釋放計時器可在 10 秒內自動到期 vgem 隔離。
在某些狀況下可在 IRQ 內容中執行除非使用 TIMER_IRQSAFE否則並不安全。BAT 在機器 bat-adlp-6 上執行作為 dma-fence-chain 自我測試之某些有問題測試案例的使用者空間取代項時在 Intel DRM CI trybot 中執行[1].
