ESET researchers discovered new variants of the Kr .k information disclosure vulnerability discovered by ESET in February 2020. The vulnerability can be used by attackers to decrypt some WPA2-encrypted wireless network packets transmitted by vulnerable devices after successful exploitation. The number of Wi-Fi-enabled devices exposed to the vulnerability exceeded one billion according to a conservative estimate provided by the researchers. Qualcomm and MediaTek radios used in vehicles, navigation systems, watches, laptops, smartphones, routers, and other devices also vulnerable.
