AMD Alerts Users to New Transient Scheduler Vulnerabilities Affecting Various CPU Models

Date: July 10, 2025
Category: Vulnerability / Hardware Security

AMD has issued a warning regarding a fresh wave of vulnerabilities impacting a wide array of chipsets, posing risks of data exposure. These vulnerabilities, known as Transient Scheduler Attacks (TSA), exploit speculative execution timing under certain microarchitectural conditions, creating a potential side channel in the CPUs. “In some instances, attackers could leverage this timing data to extract information from different contexts, leading to data leaks,” AMD stated in its advisory. The vulnerabilities were identified through research conducted by Microsoft and ETH Zurich, which tested modern CPUs against speculative execution threats like Meltdown and Foreshadow by examining isolation among security domains, including virtual machines, kernels, and processes. Following responsible disclosure in June 2024, the vulnerabilities have been assigned the following CVE identifiers: CVE-2024-36350 (CVSS score: 5.6).

⚡ Weekly Overview — SharePoint Breach, Spyware Issues, IoT Exploits, DPRK Fraud, Crypto Threats, and More

📅 July 28, 2025

Some threats don’t breach the perimeter—they slip in through signed software, polished resumes, or approved vendors that remain hidden in plain sight. This week, the most significant dangers weren’t the ones making the most noise—they were the ones that looked the most legitimate. In a landscape where identity, trust, and tools are interconnected, the strongest attack vectors often appear entirely credible. Security teams now face the challenge of defending systems not only from intrusions but from the very essence of trust being weaponized.

⚡ Threat of the Week Microsoft SharePoint Breaches Linked to China — The repercussions of an attack wave targeting vulnerabilities in on-premises Microsoft SharePoint servers continue to intensify a week after the discovery of zero-day exploits, with over 400 organizations worldwide affected. These attacks have been connected to two notorious Chinese hacking groups, Linen Typhoon (APT27) and Violet Typhoon (APT31), along with a suspected China-based threat actor known as Storm-2603.

Weekly Recap — SharePoint Breach, Spyware, IoT Hijacks, DPRK Fraud, Crypto Drains, and More July 28, 2025 Cybersecurity threats are increasingly sneaking through the back door, penetrating defenses via seemingly legitimate vectors such as signed software, polished resumes, and authorized vendors that often remain unnoticed. This week underscored that the…
