A vulnerability was found in Open5GS up to 2.7.1. This affects the function hss_ogs_diam_s6a_air_cb/hss_ogs_diam_s6a_ulr_cb of the file src/hss/hss-s6a-path.c of the component Diameter S6a Interface. Performing a manipulation of the argument os.len results in stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been made public and could be used. Upgrading to version 2.7.2 is able to mitigate this issue. The patch is named e89aa79efe629ae90f59dcdf8847c117d9a7da86. It is suggested to upgrade the affected component.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first.

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Data Freshness Timeline
(refreshed 8× in last 7d / 56× in last 30d)
Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.
Showing the most recent 96 of 174 refreshes on record for this CVE.
A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 4 repeat rows among the latest 100 are merged into the row they repeat. The 78 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
