The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets.
結論預警: CVE-2011-3188 綜合評估為高風險（68.8/100）：CVSS 技術影響為嚴重級，利用機率偏高（EPSS 5.80%，百分位 92%） 核心證據: EPSS 顯示該漏洞近期被利用的可能性處於高位。 強制指令: 被利用機率偏高—請盤點暴露面並優先安排修補。
