Soiled Pipe is among the most extreme vulnerabilities to hit the Linux kernel in a number of years. The bug lets an unprivileged person overwrite information that’s purported to be read-only, an motion that may result in privilege escalation. The bug was nailed down on February 19, and for Linux flavors like Unbuntu, a patch was written and rolled out to finish customers in about 17 days. Android relies on Linux, so Google and Android OEMs want to repair the bug, too.

It has been a full month because the Linux desktop rollout, so how is Android doing?

In response to the timeline given by Max Kellermann, the researcher who found the vulnerability, Google mounted Soiled Pipe within the Android codebase on February 23. However the Android ecosystem is notoriously dangerous at truly delivering up to date code to customers. In some sense, Android’s slowness has helped with this vulnerability. The bug was launched in Linux 5.8, which was launched in August 2020. So why did not the bug unfold far and vast throughout the Android ecosystem during the last two years?

Android’s Linux assist solely jumped from 5.4 to five.10 with the discharge of Android 12 six months in the past, and Android telephones sometimes do not soar main kernel variations. Solely brand-new telephones get the newest kernel, and so they then are likely to coast alongside on minor long-term assist updates till they’re retired.

The slowness of Android’s kernel rollouts implies that solely brand-new 2022 handsets are affected by the bug—meaning units on the 5.10 kernel, just like the Google Pixel 6, Samsung Galaxy S22, and the OnePlus 10 Professional. The vulnerability has already been changed into a working root exploit for the Pixel 6 and S22.

So the place is the patch? It hit the Android codebase on February 23 after which did not ship within the March safety replace. That may have been a quick turnaround time, however the April safety replace is now out, and Soiled Pipe, CVE-2022-0847, nonetheless is not anyplace to be discovered on Google’s safety bulletin.

The corporate hasn’t replied to our (or different publications’) questions on what occurred to the patch, nevertheless it’s affordable to anticipate that the Pixel 6 ought to have the repair by now. It is a Google telephone with a Google chip operating a Google OS, so the corporate ought to have the ability to get the replace out the door rapidly. As soon as the repair hit the codebase in late February, many third-party ROMs like GrapheneOS had been in a position to combine the patch in early March.

It seems to be like Samsung truly beat Google to releasing the patch, too. Samsung lists a patch for CVE-2022-0847 in its personal safety bulletin, indicating that the repair is rolling out to the Galaxy S22. Samsung splits vulnerabilities into Android bugs and Samsung bugs, and it says that CVE-2022-0847 is contained in Google’s April Android safety bulletin, though that is not true. Both Samsung cherry-picked the patch and did not point out that in its bulletin, or Google pulled the bugfix on the final second from the Pixel 6.

The Pixel 6 being the final telephone to get an replace would definitely be on-brand for Google, as the corporate has frequently struggled to get updates for its new flagship out on time. The telephone’s December and January patches arrived weeks late, though speedy updates are purported to be a serious promoting level of the Pixel line. Pixel updates ought to come rapidly as a result of Google controls the {hardware} and software program, and with the Pixel 6, the corporate additionally began designing its personal SoC with the assistance of Samsung. Google has fewer outdoors firms to coordinate with than ever, nevertheless it nonetheless cannot push Android updates as rapidly because it ought to.

The patch hit Android’s supply code repository 40 days in the past. Now that the bug is public and free for anybody to take advantage of, it looks like Google must be transferring quicker to offer the repair.
