The ipv6_hop_jumbo function in net/ipv6/exthdrs.c in the Linux kernel before 2.6.22 does not properly validate the hop-by-hop IPv6 extended header, which allows remote attackers to cause a denial of service (NULL pointer dereference and kernel panic) via a crafted IPv6 packet.
結論預警: CVE-2007-4567 綜合評估為高可利用風險（84.9/100）：CVSS 技術影響為高級，利用機率偏高（EPSS 14.34%，百分位 96%） 核心證據: 已收錄 1 筆公開利用參考（Exploit-DB）。 近一日 EPSS 上升 +7.12%，被利用關注度持續升高。 強制指令: 存在公開利用—請盤點暴露面、落實緩解措施並優先修補。
