1. 概述：
中標麒麟高級服務器操作系統V6有 Linux kernel 可用的更新。
中標麒麟高級服務器操作系統V7有 Linux kernel 可用的更新。
中標軟件產品安全經評定此更新對產品安全有重要意義。
2. 相關版本/架構：
中標麒麟高級服務器操作系統V6-X86_64。
中標麒麟高級服務器操作系統V7-X86_64。
3. 描述：
在Linux內核中的V4L2視頻驅動程序的ICOTL處理代碼的32位兼容層中發現了一個bug。一種確保用戶提供的緩沖區總是指向用戶空間內存的內存保護機制被禁用，允許目標地址位于內核空間中。攻擊者可以利用此缺陷從非特權用戶空間進程重寫內核內存，從而導致權限升級。
