Realtek | Vulnerability | 25 | 6/2025 | REA739060225 | Link | ||
Rankiteo Explanation : Attack without any consequences: Attack in which data is not compromisedDescription: A high-severity vulnerability has been discovered in Realtekโs Bluetooth HCI Adaptor that allows local attackers to delete arbitrary files and potentially escalate privileges on affected systems. The vulnerability, tracked as CVE-2024-11857, was published to the GitHub Advisory Database and represents a significant security risk for systems utilizing Realtek Bluetooth hardware components. The flaw stems from a Link Following weakness classified under CWE-59 in the Common Weakness Enumeration database. This flaw enables local attackers with regular user privileges to exploit the Bluetooth HCI Adaptorโs file handling mechanisms through symbolic link manipulation. The attack vector requires minimal complexity and no user interaction, making it particularly concerning for security professionals. |

What Do We Measure?
Every week, Rankiteo analyzes billions of signals to give organizations a sharper, faster view of emerging risks. With deeper, more actionable intelligence at their fingertips, security teams can outpace threat actors, respond instantly to Zero-Day attacks, and dramatically shrink their risk exposure window.
These are some of the factors we use to calculate the overall score:
Identify exposed access points, detect misconfigured SSL certificates, and uncover vulnerabilities across the network infrastructure.
Gain visibility into the software components used within an organization to detect vulnerabilities, manage risk, and ensure supply chain security.
Monitor and manage all IT assets and their configurations to ensure accurate, real-time visibility across the company's technology environment.
Leverage real-time insights on active threats, malware campaigns, and emerging vulnerabilities to proactively defend against evolving cyberattacks.
