UBUNTU-CVE-2025-27558: Medium severity ubuntu/linux-azure vulnerability

Q: Which environments are exposed to this issue?

The issue applies to mesh networks protected with WEP, WPA, WPA2, or WPA3 where devices support receiving non-SSP A-MSDU frames. The affected Ubuntu kernel packages listed are linux, linux-aws-fips, linux-azure, linux-azure-fips, linux-fips, linux-gcp, linux-gcp-fips, linux-oracle, and linux-azure.

Q: What does an attacker need to exploit the vulnerability?

An adversary needs network-level access sufficient to target the Wi-Fi mesh network. No privileges or user interaction are required according to the supplied severity vector.

Q: What is the practical impact of successful exploitation?

An attacker can inject arbitrary frames toward devices that accept non-SSP A-MSDU frames. The provided vector indicates low impact to integrity and no indicated impact to confidentiality or availability.

Updated

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.
