# vsomeip: remote TCP packet forces massive memory allocation and service crash

Link for people: https://infrastack.ai/live/CVE-2026-91141 (this .md is for agents)

vsomeip, a SOME/IP middleware library used in automotive and embedded systems, trusts a length field in incoming TCP packets. A remote attacker can send a small packet declaring a huge length, making the service allocate large memory and get killed or exhaust host memory.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
