Mitchell Frank and Mark Leonard of Cisco discovered these vulnerabilities. Blog by Jon Munshaw.
Cisco Talos recently discovered two denial-of-service vulnerabilities in the open-source program W1.fi. Both of these vulnerabilities target hostapd. One could allow an attacker to forge authentication requests, while another could trigger a deauthentication, both resulting in a denial of service.
In accordance with our coordinated disclosure policy, Cisco Talos worked with the manager of W1.fi to ensure that these issues are resolved and that an update is available for affected customers. TALOS-2019-0849 relates to TALOS-2019-0900, a denial-of-service vulnerability in the Linux kernel. Linux has also release
