Affected: AlmaLinux:10: python3-rrdtool, AlmaLinux:10: rrdtool, AlmaLinux:10: rrdtool-devel, AlmaLinux:10: rrdtool-doc, AlmaLinux:10: rrdtool-lua, AlmaLinux:10: rrdtool-perl, AlmaLinux:10: rrdtool-ruby, AlmaLinux:10: rrdtool-tcl

The round robin database (RRD) system stores and displays time-series data, such as network bandwidth, machine-room temperature, and server load average. RRDtool is a high performance data logging and graphing utility, which can be easily integrated with shell scripts, or used to create applications using its Perl, Python, Ruby, Lua, Tcl, and PHP bindings. The data is stored in a compact manner that does not expand over time, and RRDtool provides the user with useful graphs by processing the data to enforce a certain data density.

Security Fix(es):

* rrdtool: Stack buffer overflow in rrdcached handle_request_create() allows local privilege escalation via unbounded DS/RRA arguments (CVE-2026-43958)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in rrdcached, a component of rrdtool. A local attacker with access to a rrdcached socket can exploit a stack-based buffer overflow by sending an oversized CREATE request. This vulnerability can lead to a denial of service by crashing the daemon or potentially allow for arbitrary code execution, impacting the integrity and confidentiality of data.
