EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

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.

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every canonical ubuntu linux deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

  2. Fix

    Apply the canonical ubuntu linux security patch or hotfix for CVE-2010-3904 on the affected version, following the vendor advisory for your exact build.

  3. Workarounds

    Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

  4. How O3 protects you

    O3 detects and blocks CVE-2010-3904 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Tailored to CVE-2010-3904. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

O3 Security · Runtime Protection

Is CVE-2010-3904 being exploited in your environment?

O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2010-3904 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
