Description Wolfgang Frisch 2020-03-09 17:11:09 UTC
CVE-2019-9502

The Broadcom wl WiFi driver is vulnerable to a heap buffer overflow. If the
vendor information element data length is larger than 164 bytes, a heap buffer
overflow is triggered in wlc_wpa_plumb_gtk. In the worst case scenario, by
sending specially-crafted WiFi packets, a remote, unauthenticated attacker may
be able to execute arbitrary code on a vulnerable system. More typically, this
vulnerability will result in denial-of-service conditions.
