# CVE-2010-3904: Linux Kernel Improper Input Validation > Local attackers can gain privileges via crafted system calls due to improper address validation in the Linux kernel RDS protocol. - **Severity:** High 7.8 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H`) - **Exploited in the wild:** Yes, since 12 May 2023 (CISA KEV) - **Login needed:** Any signed-in user - **Attackable:** Local or same network only - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 6 Dec 2010 - **Updated:** 22 Oct 2025 - **Also known as:** GHSA-92x6-4gf8-7hcj, RHSA-2010:0792 ## What is CVE-2010-3904? CVE-2010-3904 is a high-severity vulnerability in Canonical Ubuntu Linux, published on 6 Dec 2010. It can only be exploited from the same machine or local network, with no action from the victim. ### Official 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. Weakness: CWE-1284 (Improper Validation of Specified Quantity in Input) ## Which versions are affected by CVE-2010-3904?

What it is: CVE-2010-3904 is a high-severity vulnerability in Canonical Ubuntu Linux, published on 6 Dec 2010. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: Yes. Attackers have exploited CVE-2010-3904 in the wild since at least 12 May 2023. Affected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
