CVE-2025-27558

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-27558
IEEE P802.11-REVme D1.1 through D7.0 allows FragAttacks against mesh networks. In mesh networks using Wi-Fi Protected Access (WPA, WPA2, or WPA3) or Wired Equivalent Privacy (WEP), an adversary can exploit this vulnerability to inject arbitrary frames towards devices that support receiving non-SSP A-MSDU frames. NOTE: this issue exists because of an incorrect fix for CVE-2020-24588. P802.11-REVme, as of early 2025, is a planned release of the 802.11 standard.

Summary
  • (es) IEEE P802.11-REVme D1.1 a D7.0 permite ataques FragAttack contra redes en malla. En redes en malla que utilizan Acceso Protegido Wi-Fi (WPA, WPA2 o WPA3) o Privacidad Equivalente por Cable (WEP), un atacante puede explotar esta vulnerabilidad para inyectar tramas arbitrarias en dispositivos que admiten la recepción de tramas A-MSDU no SSP. NOTA: Este problema existe debido a una corrección incorrecta para CVE-2020-24588. P802.11-REVme, a principios de 2025, es una versión planificada del estándar 802.11.
