This can\ncause problems with apps over IPv6. As for the only\nofficial app in the kernel tree (FTP) this problem is\nharmless because we use Netfilter to mangle the FTP\nports and we do not adjust the TCP seq numbers.\n\nAlso, provide correct offset of the ICMPV6 header in\nip_vs_out_icmp_v6() for correct checksum checks when\nthe IPv6 packet has extension headers.","published":"2026-08-15T06:20:47.000Z","lastModified":"2026-10-19T22:17:21.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-20"],"affected":[],"epss":{"score":0.00714,"percentile":0.53407,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.71%).
