Security researcher Doyeon Park disclosed a CVSS 7.1 zero-day in Cosmos' CometBFT causing potential node freezes during sync; vendor resistance, downgrades, and disclosure led to April 21 reveal; validators should avoid restarts before patch. Abstract: Security researcher Doyeon Park disclosed a critical CVSS 7.1 zero-day vulnerability in Cosmos' CometBFT consensus layer that could cause nodes to freeze during block synchronization, potentially affecting networks securing over $8 billion in assets. The vulnerability cannot directly steal funds. Park pursued coordinated disclosure beginning Feb 22, but faced vendor resistance to public disclosure and issues with HackerOne. The vendor downgraded a related vulnerability (CVE-2025-24371) to informational on Mar 6, prompting Park to release a network-level proof-of-concept before public disclosure on Apr 21. The advisory recommends Cosmos validators avoid restarting nodes until patches are released; nodes already in consensus may continue but restart and resync could expose them to attacks by malicious peers, risking deadlock.

AI demand boosted Korea's semiconductor exports and profits for Samsung and SK hynix; shipments to China and the US rose. Yet policy risks from U.S. tariffs loom despite a record 2025 level. Abstract: The article reports that South Korea's semiconductor exports surged in early April, driven by AI-related demand that increased memory-chip shipments and profits for Samsung Electronics and SK hynix. Exports rose to US$18.3 billion in April 1–20, with total exports up 49.4% to US$50.4 billion and a US$10.4 billion trade surplus. China and the United States were primary growth markets, and 2025 semiconductor exports reached a record US$173.4 billion, up over 20% year over year. However, policy uncertainties persist: a 25% U.S. tariff on certain advanced computing chips could affect sentiment, memory-chip exports being excluded, and tensions in the Middle East and broader tariff policies could weigh on the outlook.
