CVE-2007-3107 Denial of service in n/a
Low 2.1
Published
Updated
Check this codebase for CVE-2007-3107 and fix it if it is affected.
What it is: CVE-2007-3107 is a low-severity denial of service vulnerability in Linux kernel, published on 10 Jul 2007. 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-2007-3107 in the wild and no public exploit code.
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.

What is CVE-2007-3107?
CVE-2007-3107 is a low-severity denial of service vulnerability in Linux kernel, published on 10 Jul 2007. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The signal handling in the Linux kernel before 2.6.22, including 2.6.2, when running on PowerPC systems using HTX, allows local users to cause a denial of service via unspecified vectors involving floating point corruption and concurrency, related to clearing of MSR bits.

How do I fix CVE-2007-3107?
Upgrade to a fixed version.
Upgrade, then put limits on request size, rate and nesting depth so one client cannot exhaust the service. More about Denial of service.
Is CVE-2007-3107 being exploited?
There is no known exploitation of CVE-2007-3107 in the wild and no public exploit code.
