Detailsinfo

A vulnerability, which was classified as problematic, has been found in Netdata up to 2.10.3. Affected by this issue is the function pluginsd_rrdset_cache_put_to_slot of the file src/plugins.d/pluginsd_internals.h of the component Pluginsd Internals. The manipulation with an unknown input leads to a allocation of resources vulnerability. Using CWE to declare the problem leads to CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. Impacted is availability. CVE summarizes:

Netdata is an open source observability tool. Prior to 2.10.4, an authenticated child agent can send an oversized CHART SLOT value that str2ull_encoded passes to pluginsd_rrdset_cache_put_to_slot in src/plugins.d/pluginsd_internals.h. The accepted slot drives reallocz to request an approximately 16 GiB chart-pointer array, and allocation failure invokes fatal and aborts the parent Netdata agent, repeatedly disabling centralized monitoring while stream access persists. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-83600 since 08/31/2026. The exploitation is known to be easy. The attack may be launched remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.

Upgrading to version 2.10.4 eliminates this vulnerability.
