Samsung and Google disagree on whether or not Soiled Pipe vulnerability has been mounted in current patches

Though updates for Pixels and Samsung telephones have been rolled out with April 2022 patch ranges included, there was plenty of confusion over a major and extremely publicized safety vulnerability. Though the April Android Safety Bulletin was launched in the present day, it doesn’t state that it fixes the Soiled Pipe vulnerability, which can be utilized to execute arbitrary code. Samsung, however, says Google’s fixes within the April publication do Soiled Pipe tackle, and the Galaxy S22 sequence is now not affected.

For the uninitiated, Google is rolling out a giant “patch stage” for Android that features patches for safety vulnerabilities each month. Smartphone makers get early entry to roll out updates in a coordinated vogue at the beginning of every month, assuming they supply month-to-month updates. (Some producers apply these adjustments to much less premium units and ship them each two months, or as soon as 1 / 4.) Every month, Google points a bulletin that explains which vulnerabilities have been mounted within the month-to-month patch ranges offered. Every month’s scores checklist the vulnerability sort, severity, and assigned CVE ID, and this month’s scores from Google for April 2022 are lacking CVE-2022-0847.


This identifier is linked to the Soiled Pipe vulnerability, which researchers exploited to fully root a Google Pixel 6 Professional and Samsung’s Galaxy S22 sequence by making the most of a bug in the way in which Linux handles studying and writing within the recordsdata. Performed proper, the exploit can permit elevation of privilege and execution of arbitrary code – spooky phrases that mainly imply {that a} malicious actor can use the exploit to take full management of a system (and lovers can use it to realize root entry).

With the complete documentation at present out there relating to the exploit and its affect on programs working particular variations of the Linux kernel, it may be used “within the wild” by malicious actors, though it’s much less doubtless that somebody l are at present utilizing to focus on Android. Telephone(s. The vulnerability requires a really current model of the Linux kernel, and Android telephones are inclined to “reside” on a single model for many of their life. Excluding the Pixel 6 and its assist From the generic kernel picture, solely telephones with a Snapdragon 8 Gen 1 working on Android 12 or later must be affected.This consists of the Galaxy S22 sequence, Xiaomi 12 Professional, OnePlus 10 Professional, and the Pixel 6 and 6 Professional powered by Google’s Tensor.

The April 2022 Android safety bulletin doesn’t embrace fixes for the CVE that corresponds to the Soiled Pipe vulnerability, nor are they talked about within the separate, device-specific Pixel replace bulletin. Esper.io’s Mishaal Rahman additional confirmed that the kernel construct date and present patch tags on the Pixel 6 Professional point out that it has remained unchanged and is unlikely to incorporate patches for Soiled Pipe. Nevertheless, Samsung’s patch notes and documentation for the April replace on the Galaxy S22 sequence explicitly say so. at was mounted there. Even stranger, nonetheless, Samsung’s documentation bluntly states that Google mounted it. at its finish with the April 2022 Replace, at odds with Google’s personal documentation.

In brief: Samsung says Google mounted it and, by omission, Google says it didn’t.

We’ve reached out to Google to verify extra explicitly whether or not the Soiled Pipe vulnerability has been mounted within the newest patch stage, in addition to whether or not the Pixel 6 remains to be affected, however firm reps haven’t responded to our (repeated) requests. . We’ve additionally reached out to Samsung for extra info on the S22 sequence, and the corporate is wanting into the matter.

Though only some very current (and comparatively high-end) telephones are affected, given the severity of the vulnerability, many purchasers have been hoping it may very well be patched throughout the board with this month’s replace. , after its public disclosure on March 7. However the scenario remains to be murky, and whereas it impacts buyer safety, Google isn’t doing a lot to clear it up.

Samsung says Google mounted it, Google web page disagrees

As noticed by SamMobile, Samsung says so at mounted the Galaxy S22 sequence vulnerability within the newest replace. Samsung’s safety updates web page even consists of the CVE for Soiled Pipe. Extra unusually, Samsung explicitly says the patch is a part of Google’s April 2022 Android Safety Bulletin, despite the fact that Google’s web page for that particularly makes no point out of it.

Now we have (once more) contacted Google for extra info, however the firm remains to be unresponsive to our requests, though a bit communication might simply resolve this difficulty.

Our protection above has been up to date.
