CVE-2016-4565 Memory corruption in n/a
High 7.8
Published
Updated
Check this codebase for CVE-2016-4565 and fix it if it is affected.
What it is: CVE-2016-4565 is a high-severity memory corruption vulnerability in Canonical Ubuntu Linux, published on 23 May 2016. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2016-4565 in the wild and no public exploit code.
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.

What is CVE-2016-4565?
CVE-2016-4565 is a high-severity memory corruption vulnerability in Canonical Ubuntu Linux, published on 23 May 2016. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The InfiniBand (aka IB) stack in the Linux kernel before 4.5.3 incorrectly relies on the write system call, which allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface.
Weakness: CWE-264
