CVE-2022-24512 has a CVSS score of 6.3/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2022-24512?

CVE-2022-24512 affects the following packages: Microsoft.NETCore.App.Runtime.linux-arm (NuGet), Microsoft.NETCore.App.Runtime.linux-arm64 (NuGet), Microsoft.NETCore.App.Runtime.linux-musl-arm64 (NuGet), Microsoft.NETCore.App.Runtime.linux-musl-x64 (NuGet), Microsoft.NETCore.App.Runtime.linux-x64 (NuGet), Microsoft.NETCore.App.Runtime.osx-x64 (NuGet), Microsoft.NETCore.App.Runtime.win-arm (NuGet), Microsoft.NETCore.App.Runtime.win-arm64 (NuGet), and 139 more. Ecosystems affected: NuGet.

How do I fix CVE-2022-24512?

Update Microsoft.NETCore.App.Runtime.linux-arm to 3.1.23 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-24512 is resolved across your whole dependency graph.

How do I detect CVE-2022-24512 in my NuGet dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Microsoft.NETCore.App.Runtime.linux-arm, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2022-24512 if there is no patch (or I can't update yet)?

Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.

Is CVE-2022-24512 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-24512 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2022-24512?

CVE-2022-24512 has an EPSS (Exploit Prediction Scoring System) score of 1.6%, placing it in the 76th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2022-24512?

CVE-2022-24512 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2022-24512 published, and has it been updated?

CVE-2022-24512 was published on March 9, 2022 and was last updated on October 24, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
