In version 1.6.0 and earlier, the sFlow ExtendedGatewayFlow decoder in layers/sflow.go reads an attacker-controlled 32-bit community count and AS path member count and sizes a slice allocation from those counts without bounding them against the bytes remaining in the datagram, so a 104-byte UDP datagram can drive an allocation of up to 16 GiB and cause an unauthenticated remote denial of service. This issue is fixed in version 1.6.1.","published":"2026-07-28T17:16:51.000Z","lastModified":"2026-08-05T19:10:43.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":6.9,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-770"],"affected":["gopacket/gopacket"],"epss":{"score":0.0079,"percentile":0.56,"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":"low","text":"Lower severity and a low EPSS score (0.79%).
