CVE-2018-5390 Denial of service in Linux Kernel
High 7.5
Published
Updated
Check this codebase for CVE-2018-5390 and fix it if it is affected.
What it is: CVE-2018-5390 is a high-severity denial of service vulnerability in Canonical Ubuntu Linux, published on 6 Aug 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-5390 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-2018-5390?
CVE-2018-5390 is a high-severity denial of service vulnerability in Canonical Ubuntu Linux, published on 6 Aug 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service.
Weakness: CWE-400
