1. 概述：

中標麒麟高級服務器操作系統(tǒng)V6有 Linux kernel 可用的更新。
中標麒麟高級服務器操作系統(tǒng)V7有 Linux kernel 可用的更新。
中標軟件產(chǎn)品安全經(jīng)評定此更新對產(chǎn)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(tǒng)V6-X86_64。
中標麒麟高級服務器操作系統(tǒng)V7-X86_64。

3. 描述：
Linux內(nèi)核中net/ipv4 /inet_connection_sock.c中的inet_csk_clone_lock函數(shù)允許攻擊者通過利用accept系統(tǒng)調(diào)用來導致拒絕服務（雙重釋放）或可能具有未指定的其他影響。 沒有特權的本地用戶可能會利用此漏洞在系統(tǒng)上引發(fā)內(nèi)核內(nèi)存損壞，從而導致崩潰。由于缺陷的性質，特權升級不能完全排除，盡管可能性不大。
