# CVE-2026-0031

> 8.4 HIGH

## Beschreibung

In multiple functions of mem_protect.c, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

## Schwachstellen-Klasse

- **CWE-190** — Integer Overflow or Wraparound
  The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

## Angriffsmuster (CAPEC)

- [CAPEC-92 — Forced Integer Overflow](https://capec.mitre.org/data/definitions/92.html) _(Severity: High)_

## BSI-Hinweise (deutsch)

- [Google Android: Mehrere Schwachstellen](https://wid.cert-bund.de/portal/wid/sicherheitshinweis/WID-SEC-W-2026-0569) — _BSI-Einstufung: kritisch_
  Ein Angreifer kann mehrere Schwachstellen in Google Android ausnutzen, um sich erweiterte Berechtigungen zu verschaffen, beliebigen Code auszuführen, einen Denial-of-Service-Zustand zu verursachen, vertrauliche Informationen offenzulegen oder andere nicht näher spezifizierte Angriffe durchzuführen.
