About CVE-2010-3904

CVE-2010-3904 is a critical local privilege escalation vulnerability in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. The vulnerability is specifically located in the rds_page_copy_user function, where inadequate validation of addresses obtained from user space allows a potential attacker to craft and send a malicious packet to the target system, thereby gaining elevated privileges.

The exploitation process for CVE-2010-3904 is relatively straightforward. An attacker simply needs to transmit the specially-crafted packet to the vulnerable system. Upon receipt, the vulnerability will be exploited, providing the attacker with elevated privileges on the system.

The consequences of not addressing CVE-2010-3904 are severe and could lead to various malicious activities, including installing malware, stealing sensitive data, and disrupting operations.

To protect your system from this vulnerability, you should update the Linux kernel to version 2.6.36 or later.
