NVD Description
Note: Versions mentioned in the description apply only to the upstream grafana-12.1-oci-compat package and not the grafana-12.1-oci-compat package as distributed by Minimos.
Tempo queries with large limits can cause large memory allocations which can impact the availability of the service, depending on its deployment strategy.
Mitigation can be done by setting max_result_limit in the search config, e.g. to 262144 (2^18). Alternatively, automatically restart the service.
