AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-8300 is a heap-based buffer overflow vulnerability in the Realtek rtl81xx SDK Wi-Fi driver, specifically in the N6CSet_DOT11_CIPHER_DEFAULT_KEY function. The flaw occurs because the driver does not properly validate the length of user-supplied data before copying it into a fixed-length heap buffer. An attacker who already has the ability to execute low-privileged code locally can exploit this vulnerability to escalate their privileges to SYSTEM level and execute arbitrary code with full system privileges. [1]
How can this vulnerability impact me? :
This vulnerability can allow a local attacker with low privileges to escalate their privileges to SYSTEM level on an affected system. This means the attacker can execute arbitrary code with full system privileges, potentially leading to complete system compromise, unauthorized access to sensitive data, and disruption of system operations.
