CVE-2019-17133: Buffer Overflow

First published: Fri Oct 04 2019(Updated: )

Linux Kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the cfg80211_mgd_wext_giwessid functions in net/wireless/wext-sme.c. By sending an overly long long SSID IE, a remote attacker could overflow a buffer and execute arbitrary code on the system.
