Hey,
Has anyone explained how zergrush works. I was wondering if someone has explained it. I want to understand how the linux vulnerability is exploited.
If you are a developer, the best way is to read through the source found in the developer's git repo here:
https://github.com/revolutionary/zergRush
mods: maybe this could get moved to Android Dev and Hacking/Misc Dev? This is my first post, and there's a minimum 10 post rule to post on the dev forums. I searched the forums and could not find a similar post, and it could be useful for ROM hackers.
I've been keeping track of a few upcoming risky vulnerabilities that modern devices may be vulnerable to, and possible patches. For those of you that embed custom kernels in your ROM, or want a secure kernel for your custom ROM, this should be useful. Hopefully we can have people chime in and post patches they think are needed. Now, these may be commonly used to root your device, but for those of you creating pre-rooted ROMs, you will probably want the patch to protect your devices from malicious activity.
http://www.cvedetails.com/cve/CVE-2012-4220/ also 4221 and 4222:
affects Android versions from 2.3 to 4.2 with a Qualcomm processor
patch here: https://www.codeaurora.org/particip...es/cve-2012-4220-cve-2012-4221-cve-2012-4222/
code execution, local priv, DoS
http://www.cvedetails.com/cve/CVE-2011-3874/
the infamous zergRush exploit for the vulnerability in libsysutils.so
PoC: https://github.com/revolutionary/zergRush/blob/master/zergRush.c
patch: http://code.google.com/p/android/issues/attachmentText?id=21681&aid=216810001000&name=patch.diff&token=zyMox2r00ZIPN7qD_zdjHy2cf10%3A1358973107051
affects Froyo and Gingerbread, which a lot of people are still working with. As a ROM dev, you might not be working with older Android versions, but this allows code execution.
samsung exynos flaw - I don't see a CVE for this yet
http://forum.xda-developers.com/showthread.php?t=2048511
"This device is R/W by all users and give access to all physical memory"
patch here, but another patch in that thread as well: http://review.cyanogenmod.org/#/c/29910/
"Ram dump, kernel code injection and others could be possible via app installation from Play Store" ouch
2012 CVEs:

Anyone else know some good vulns and patches??
Hope this is helpful!

I just installed Belarc Security and it discovered the first issues with the two others, 4220. 4221, 4222, not sure if I should be concerned...
Hi,
An issue on qualcomm has been addressed to CodeAurora more than one month now.
You will find details and patch about issue here for custom kernel developpers.
I have published an exploit (named Gandalf) in Framaroot to root vulnerable Qualcomm based devices, you can download the apk in this thread and give feedbacks if it work on your device.
Google released the patch ASB-2019-08-05 that fix several bugs that could allow for escalation of privilege.
https://source.android.com/security/bulletin/2019-08-01.html
Those are:
CVE-2019-2120
CVE-2019-2121
CVE-2019-2122
CVE-2019-2125
CVE-2019-2128
CVE-2019-2131
CVE-2019-2132
CVE-2019-2133
CVE-2019-2134
CVE-2019-2127
The patch commit is located here:
https://android.googlesource.com/kernel/common/+/refs/tags/ASB-2019-08-05_4.4
and diffs here:
https://android.googlesource.com/ke...19-08-05_4.4^1..refs/tags/ASB-2019-08-05_4.4/
or
https://android.googlesource.com/ke...19-08-05_4.4^2..refs/tags/ASB-2019-08-05_4.4/
For those who did not apply the patch, it's a chance to root devices, like me who have a locked Verizon Pixel 2 XL.
I'm sharing the idea here in case someone can do it quicker, as I know there are people here with much more hacking knowledge than me.
Anyway, I will look into how to exploit it to get root privilege.
The kernel exploit has just been released and wondered if there were any devs about who know how to incorporate this into the quest?
As my post level is low.....search google for Github QuestEscape exploit

Custom FW
Waiting ansiously for a custom fw to Oculus Quest. I hope any dev can do this soon.
