NewCVE-2026-83601 (opens in a new tab)How to fix?
There is no fixed version for Debian:12 netdata.
NVD Description
Note: Versions mentioned in the description apply only to the upstream netdata package and not the netdata package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
Netdata is an open source observability tool. 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.
