Why this deserves its current priority

A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Analysis status

Analysis pending evidence review

Factual feed record only; HOL analysis is not approved for indexing. Read the methodology.

Affected scope and exposure questions

The current feed maps COVESA/vSomeIp (generic). Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions
PackageAffected rangeFixed version

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for COVESA/vSomeIp.
  2. 2Review the reported fix. Update COVESA/vSomeIp to 3.7.4 if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

  • Source referencebiackr0se.github.io
  • Source referencekb.cert.org
Upstream source description

A vulnerability in the default configuration of vsomeip allows a remote, unauthenticated attacker to trigger massive memory allocations by sending a small TCP packet with a large, attacker-declared SOME/IP length field. This can lead to immediate service termination via OOM-kill on memory-constrained systems or total host memory exhaustion through repeated connections.
