Known exploited

CISA added this to the Known Exploited Vulnerabilities Catalog on 12 May 2023. US federal agencies had to remediate by 2 Jun 2023, a deadline that has passed.

Required action. The impacted product is end-of-life and should be disconnected if still in use.

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.

This page tells you how dangerous CVE-2010-3904 is out there. Whether it sits on one of your devices, only a scan of your own network can tell. That is what our systems do, every day, for the companies we protect.

CVE-2010-3904 is in the CISA catalogue of exploited vulnerabilities: attackers are already exploiting it.

  • EXYS7600 OCELOT

    Find it before attackers do

    Ocelot scans your network on a schedule and reports every vulnerability it finds by its CVE identifier, with its CVSS score and how many of your hosts are affected. A finding like CVE-2010-3904 comes with the devices to patch.
