Detailsinfo

A vulnerability, which was classified as problematic, has been found in IEEE P802.11-REVme up to D7.0. Affected by this issue is an unknown functionality of the component Mesh Network Handler. The manipulation with an unknown input leads to a injection vulnerability. Using CWE to declare the problem leads to CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. Impacted is integrity. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is handled as CVE-2025-27558 since 03/02/2025. The exploitation is known to be easy. The attack can only be done within the local network. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 01/30/2026). This vulnerability is assigned to T1055 by the MITRE ATT&CK project.
