# CVE-2008-0600: Privilege escalation in n/a > Local attackers can gain root privileges by exploiting a missing pointer validation in the Linux kernel's vmsplice system call. - **Severity:** High 7.2 (`AV:L/AC:L/Au:N/C:C/I:C/A:C`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Local or same network only - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 12 Feb 2008 - **Updated:** 7 Aug 2024 - **Also known as:** DTSA-113-1, GHSA-vv62-ccxv-738x, RHSA-2008:0129 ## What is CVE-2008-0600? CVE-2008-0600 is a high-severity vulnerability in Linux kernel, published on 12 Feb 2008. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description The vmsplice_to_pipe function in Linux kernel 2.6.17 through 2.6.24.1 does not validate a certain userspace pointer before dereference, which allows local users to gain root privileges via crafted arguments in a vmsplice system call, a different vulnerability than CVE-2008-0009 and CVE-2008-0010.

What it is: CVE-2008-0600 is a high-severity vulnerability in Linux kernel, published on 12 Feb 2008. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2008-0600 exists. Affected product: Linux kernel. 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.
