Prior to 2.10.4, an authenticated child agent can send an oversized DIMENSION SLOT value that str2ull_encoded passes to pluginsd_rrddim_put_to_slot in src/plugins.d/pluginsd_internals.h without an upper bound. prd_array_create in src/database/rrdset-pluginsd-array.h can then wrap the size_t allocation calculation while retaining the original large array size, causing the subsequent initialization loop to write beyond the undersized heap allocation and crash the parent agent. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly.","state":0,"publishedAt":"2026-09-22T17:00:51.41+00:00","modifiedAt":"2026-09-25T23:47:06.833+00:00","affected":[{"ecosystem":"Vendor product","name":"netdata","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"netdata\",\n                    \"product\": \"netdata\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.10.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/netdata/netdata/security/advisories/GHSA-3qh4-842w-fvrm","https://github.com/netdata/netdata/pull/22598","https://github.com/netdata/netdata/commit/034a774f689ac01488fc261ca729ce0875819b1b","https://github.com/netdata/netdata/releases/tag/v2.10.4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-83601","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-83601","identifiers":["CVE-2026-83601"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
