Flagship Android 12 Devices Under Threat Due to Severe ‘Dirty Pipe’ Bug

Google Pixel 6, Samsung Galaxy S22, and another new units operating on Android 12 are affected by a extremely extreme Linux kernel vulnerability referred to as “Soiled Pipe.” The vulnerability could be exploited by a malicious app to realize system-level entry and overwrite information in read-only recordsdata on the system. First seen on the Linux kernel, the bug was reproduced by a safety researcher on Pixel 6. Google was additionally knowledgeable about its existence to introduce a system replace with a patch.

Safety researcher Max Kellermann of German Net growth firm CM4all noticed the ‘Soiled Pipe’ vulnerability. Shortly after Kellermann publicly disclosed the safety loophole this week that has been recorded as CVE-2022-0847, different researchers had been in a position to element its impression.

As per Kellermann, the problem existed within the Linux kernel because the model 5.8, although it was fastened within the Linux 5.16.11, 5.15.25, and 5.10.102. It’s much like the ‘Dirty COW‘ vulnerability however is less complicated to use, the researcher mentioned.

The ‘Soiled COW’ vulnerability had impacted Linux kernel variations created earlier than 2018. It additionally impacted users on Android, although Google fastened the flaw by releasing a security patch back in December 2016.

An attacker exploiting the ‘Soiled Pipe’ vulnerability can acquire entry to overwrite information in read-only recordsdata on the Linux system. It might additionally enable hackers to create unauthorised person accounts, modify scripts, and binaries by gaining backdoor entry.

Since Android makes use of the Linux kernel as core, the vulnerability has a possible to impression smartphone customers as properly. It’s, nevertheless, restricted in nature as of now — due to the truth that most Android releases are not based on the Linux kernel versions which can be affected by the flaw.

“Android earlier than model 12 shouldn’t be affected in any respect, and a few Android 12 units — however not all — are affected,” Kellermann advised Devices 360.

The researcher additionally mentioned that if the system was weak, the bug may very well be used to realize full root entry. Which means that it may very well be used to permit an app to learn and manipulate encrypted WhatsApp messages, seize validation SMS messages, impersonate customers on arbitrary web sites, and even remotely management any banking apps put in on the system to steal cash from the person.

Kellermann was in a position to reproduce the bug on Google Pixel 6 and reported its particulars to the Android safety workforce in February. Google additionally merged the bug fix into the Android kernel shortly after it obtained the report from the researcher.

Nonetheless, it’s unclear whether or not the bug has been fastened by the March safety patch that was launched earlier this week.

Along with the Pixel 6, the Samsung Galaxy S22 units seem like impacted by the bug, according to Ars Technica’s Ron Amadeo.

Another units which can be operating on Android 12 out-of-the-box are additionally anticipated to be weak to assaults because of the ‘Soiled Pipe’ concern.

Devices 360 has reached out to Google and Samsung for readability on the vulnerability and can inform readers when the businesses reply.

In the meantime, customers are really helpful to not set up apps from any third-party sources. It is usually essential to keep away from putting in any untrusted apps and video games, and ensure to have the newest safety patches put in on the system.
