AI Analysis
Technical Summary
CVE-2026-43958 is a stack buffer overflow vulnerability in the rrdcached daemon of rrdtool. A local attacker with socket access can exploit this by sending an oversized CREATE request, leading to potential daemon crash or arbitrary code execution. The flaw is due to unbounded DS/RRA arguments in the handle_request_create() function. Red Hat has issued a security advisory (RHSA-2026:33731) providing an update that fixes this vulnerability in Red Hat Enterprise Linux 10 and related products.
Potential Impact
Successful exploitation can cause denial of service by crashing the rrdcached daemon or potentially allow local privilege escalation through arbitrary code execution. This impacts the confidentiality and integrity of the data managed by rrdtool.
Mitigation Recommendations
Red Hat has released an official security update that fixes this vulnerability. Users of affected Red Hat Enterprise Linux 10 versions should apply the update as described in the Red Hat advisory RHSA-2026:33731. No additional mitigation is required beyond applying the official patch.
