# CVE-2009-0065: Memory corruption in n/a > Remote attackers can trigger a buffer overflow in the Linux kernel SCTP implementation via a crafted chunk, potentially causing code execution or denial of service. - **Severity:** Critical 10.0 (`AV:N/AC:L/Au:N/C:C/I:C/A:C`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 7 Jan 2009 - **Updated:** 7 Aug 2024 - **Also known as:** GHSA-w8p6-7232-w86w, RHSA-2009:1055 ## What is CVE-2009-0065? CVE-2009-0065 is a critical memory corruption vulnerability in Linux kernel, published on 7 Jan 2009. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.28-git8 allows remote attackers to have an unknown impact via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID. Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) ## Which versions are affected by CVE-2009-0065?

What it is: CVE-2009-0065 is a critical memory corruption vulnerability in Linux kernel, published on 7 Jan 2009. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2009-0065 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.
