CVE-2019-9500

Priority
Description
The Broadcom brcmfmac WiFi driver prior to commit
1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable to a heap buffer
overflow. If the Wake-up on Wireless LAN functionality is configured, a
malicious event frame can be constructed to trigger an heap buffer overflow
in the brcmf_wowl_nd_results function. This vulnerability can be exploited
with compromised chipsets to compromise the host, or when used in
combination with CVE-2019-9503, can be used remotely. 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.
Ubuntu-Description
Hugues Anguelkov discovered that the Broadcom Wifi driver in the Linux
kernel contained a heap buffer overflow. A physically proximate attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code.
