Cloudera Spark GPU acceleration, 5G summits, and security advisories - Week of August 17, 2026

Overview of Recent Activity

Recent reporting covered enterprise 5G and AI infrastructure planning, network economics, and multiple security flaw disclosures. Carahsoft and FedInsider discussed Open RAN, integrated sensing and communication, and AI for 5G and 6G. Cloudera added GPU acceleration to Apache Spark 4.1 and introduced Cloudera Anywhere Cloud for production data and AI apps. CISA-related reporting described remotely exploitable UPnP exposure in a Calix residential gateway and multiple authentication and memory corruption issues in an RDK-B WebUI.

Key Themes and Developments

H3: Technology Releases & Product Enhancements

Cloudera enabled native GPU acceleration for Apache Spark 4.1 in Cloudera Data Engineering using NVIDIA CUDA-X libraries and a cuDF plug-in. Cloudera said the change would shorten processing time for Spark workloads without code changes. Cloudera also said the capability would be available as part of Cloudera Anywhere Cloud announced at EVOLVE Singapore on August 20, 2026.

Teleport added Linux Desktop support to its Infrastructure Identity Platform. Teleport described Linux desktops as operating as a protected resource type using “cryptographic identity” and “just-in-time access request workflows,” with “live session monitoring, and audit logs.” Teleport said the update was available in August.

H3: Partnerships & Ecosystem Engagement

RegScale collaborated with Microsoft to support FedRAMP readiness and authorization efforts on Microsoft Azure. The companies described FedRAMP 20x as shifting security assurance toward “continuous, automated validation.” RegScale said it mapped FedRAMP 20x principles to continuous controls validation and reporting in real time against FedRAMP’s Key Security Indicators.

Carahsoft co-hosted its fourth annual 5G Summit with FedInsider at the Carahsoft Conference & Collaboration Center in Reston. Speakers and sponsors included NTIA, Ericsson, Dell Technologies, the U.S. Army, and T-Mobile, with the agenda covering open source Open RAN, integrated sensing and communication, and AI in next-generation wireless networks.

H3: Infrastructure, Platform, or Deployment Updates

Dell’Oro Group reported that optical transport equipment revenue grew 15% year-over-year in 2Q 2026, with data center interconnect revenue from IPoDWDM ZR/ZR+ and WDM systems rising 45% year-over-year. Dell’Oro said cloud providers purchased WDM Systems and IPoDWDM ZR/ZR+ optics at double-digit year-over-year growth rates during the quarter.

Dell’Oro Group forecast worldwide data center physical infrastructure manufacturer revenue to reach $120 billion by 2030, growing at a 22% CAGR from 2025. The report attributed most growth to net additions of installed IT capacity and said delivery constraints were the main risk, citing “equipment lead times, construction labor, grid interconnection, and community consent.”

H3: Additional Updates from Other Organizations

CISA-related reporting described Calix EXOS/6.6.47 exposing UPnP WANIPConnection on TCP 5000, enabling NAT mapping changes via an unauthenticated flaw. Separate reporting said the RDK-B WebUI version rdkb-2025q4-kirkstone had multiple vulnerabilities, including improper authentication and memory corruption issues that could enable administrative access and denial-of-service.

Rapid7 reported that newly exploited vulnerabilities increased by up to 40% in Q2 2026. Rapid7 also said 62% of newly exploited vulnerabilities were categorized as “holy grail” flaws, and it reported year-over-year doubling for high and critical disclosures.
