CRE-2025-0033 Low Impact: 7/10 Mitigation: 4/10	OpenTelemetry Collector refuses to scrape due to memory pressure	The OpenTelemetry Collector may refuse to ingest metrics during a Prometheus scrape if it exceeds its configured memory limits. When the `memory_limiter` processor is enabled, the Collector actively drops data to prevent out-of-memory errors, resulting in log messages indicating that data was refused due to high memory usage.

CRE-2025-0037 Low Impact: 8/10 Mitigation: 4/10	OpenTelemetry Collector panics on nil attribute value in Prometheus Remote Write translator	The OpenTelemetry Collector can panic due to a nil pointer dereference in the Prometheus Remote Write exporter. The issue occurs when attribute values are assumed to be strings, but the internal representation is nil or incompatible, leading to a runtime `SIGSEGV` segmentation fault and crashing the collector.
