Vulnerabilites related to Broadcom - WiFi drivers
cve-2019-9502
Vulnerability from cvelistv5
Published

Severity ?
7.9 (High) - CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
Summary
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.

Severity ?
7.9 (High) - CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
Summary
The Broadcom wl WiFi driver is vulnerable to a heap buffer overflow. By supplying a vendor information element with a data length larger than 32 bytes, a heap buffer overflow is triggered in wlc_wpa_sup_eapol. 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.
