## Summary

EPICS Base, a widely used software toolkit for building control systems, is affected by this vulnerability. An attacker who sends a specially crafted network message can cause the software to crash or expose nearby memory contents.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- The EPICS Community EPICS Base: through 7.0.10

## Description

In EPICS Base release 7.0.10 and prior, an insufficient validation of element or length values in a network message can cause the application to read beyond the bounds of an allocated buffer. This may lead to denial of service and could expose adjacent memory contents.
