Security researchers from Tencent’s Blade Team are warning Android smartphone and tablet users of flaws in Qualcomm chipsets, called QualPwn. The bugs collectively allow hackers to compromise Android devices remotely simply by sending malicious packets over-the-air – no user interaction required.
Three bugs make up QualPwn (CVE-2019-10539, CVE-2019-10540 and CVE-2019-10538). The prerequisite for the attack is that both the attacker and targeted Android device must be active on the same shared Wi-Fi network.
“One of the vulnerabilities allows attackers to compromise the WLAN and modem, over-the-air. The other allows attackers to compromise the Android kernel from the WLAN chip. The full exploit chain allows attackers to compromise the Android kernel over-the-air in some circumstances,” wrote researchers.
