{"id":"CVE-2026-106806","details":"A memory exhaustion issue exists in Open5GS v2.8.0 in the HTTP/2 SBI server. Repeated header names cause previously allocated header strings to be leaked, and HPACK compression allows an unauthenticated remote attacker to trigger tens of thousands of duplicate headers with a small request. Repeated crafted requests can cause persistent heap growth, exhaust process memory, and terminate the affected Open5GS network function, resulting in denial of service.","modified":"2026-11-03T02:45:37.756090174Z","published":"2026-11-02T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/106xxx/CVE-2026-106806.json"},"references":[{"type":"WEB","url":"https://gist.github.com/hackeryounow/c923fad9de83011004bd7d078b817dc0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/106xxx/CVE-2026-106806.json"},{"type":"FIX","url":"https://github.com/open5gs/open5gs/commit/76f15375ead1b2db09193458e56640da0a86c255"},{"type":"REPORT","url":"https://github.com/open5gs/open5gs/issues/4788"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106806"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open5gs/open5gs","events":[{"introduced":"0"},{"fixed":"76f15375ead1b2db09193458e56640da0a86c255"}],"database_specific":{"extracted_events":[{"range":[{"fixed":"76f15375ead1b2db09193458e56640da0a86c255"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["v2.8.0","v2.7.7","v2.7.2","v2.7.1","v2.7.0","v2.6.6","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.4.9","v2.4.8","v2.4.7","v2.4.5","v2.4.4","v2.4.3","v2.4.1","v2.4.0","v2.3.6","v2.3.2","v2.3.0","v2.2.9","v2.2.8","v2.2.7","v2.2.6","v2.2.1","v2.2.0","v2.1.7","v2.1.5","v2.1.4","v2.1.3","v2.1.1","v2.1.0","v2.0.22","v2.0.18","v2.0.0","v1.3.0","v1.2.4","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.5.2","v0.5.1","v0.5.0","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.3.10","v0.3.8","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.0","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-106806.json"}}],"schema_version":"1.9.2"}
