OpenHarmony v6.0 and earlier contain an integer overflow in the kernel liteos a component, which allows a local attacker to trigger a denial‑of‑service condition. The weakness is identified as CWE‑190 (Integer Overflow or Wraparound). The impact is restricted to local hosts that can directly interact with the vulnerable kernel facilities; there is no evidence of remote exploitation or privilege escalation in the provided data.

The affected system is OpenHarmony OpenHarmony, specifically versions 6.0 and earlier. No additional product or vendor variations are noted.

The CVSS score of 3.3 classifies this vulnerability as low severity, and there is no EPSS data available. The vulnerability is not listed in the CISA KEV catalog, indicating low exploitation likelihood. Based solely on the description, the attack vector appears to be local; a compromise in the local environment is required to execute the integer overflow and cause a denial‑of‑service.
