Vulnerability in Qualcomm chip used in smartphones allows an attacker to inject malicious code

A vulnerability present in chips manufactured by Qualcommm Inc. which are utilized in 40% of the world’s smartphones can enable an attacker to inject malicious code.

Found and publicized at present by safety researchers at Test Level Software program Applied sciences Ltd., the vulnerability is present in Qualcomm’s cellular station modem, the chip answerable for mobile communication. MSM is designed for high-end telephones and helps superior options similar to 4G LTE and high-definition recording.

The vulnerability was found when a safety researcher went to implement a modem debugger to discover the newest 5G code. Through the investigation, it was found that the vulnerability within the modem knowledge service can be utilized to manage the modem and dynamically patch it from the appliance processor.

With this skill, attackers may inject malicious code into the modem from Android, giving them entry to the gadget consumer’s name historical past and SMS in addition to the power to hearken to the gadget consumer’s conversions. An attacker may additionally unlock the gadget’s SIM, overcoming any limitations imposed by service suppliers.

The MSM may be present in higher-end units made by Google LLC, Samsung Electronics Co. Ltd., LG Inc., Xiaomi Inc. and OnePlus Expertise Co. Ltd. The vulnerability was found in 2020 and Test Level knowledgeable Qualcomm on the time.

Qualcomm stated that it had already made fixes accessible to unique tools producers in December, although the present standing of the rollout by smartphone makers is unknown. The patch might have been rolled out to current smartphones however usually corporations abandon offering assist updates for units after a sure variety of years. That menas older units won’t obtain a safety replace and therefore stay susceptible.

“This latest safety concern with Qualcomm highlights the significance of thorough safety vetting pre and post-deployment,” Shachar Menashe, vp safety at product safety firm Vdoo Linked Belief Ltd., advised SiliconANGLE. “On this case, it appears we’re coping with a privilege escalation vulnerability, which implies it lets potential attackers run code on the Qualcomm modem if you have already got excessive privileges on the Android utility layer. ”

“Automated evaluation will help establish zero-day vulnerabilities and configuration dangers, even in closed-source parts,” Menashe added. “Producers must belief that their third-party parts are safe, particularly when these methods are utilized in almost 40% of the cell phones bought at present.”
