CVE-2010-3904

Linux Kernel Improper Input Validation Vulnerability

KEVEXPLOIT ×2 ✓HIGH 7.8EPSS 15.9%

Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 2 June 2023). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

Description

The rds_page_copy_user function in net/rds/page.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel before 2.6.36 does not properly validate addresses obtained from user space, which allows local users to gain privileges via crafted use of the sendmsg and recvmsg system calls.
