Exploitability on Android's Linux kernels
SaaS Insight & Market Implications
This inquiry probes `dirtyfrag`'s applicability to Android's Linux kernels, specifically concerning privilege escalation on ARM devices. The user's motivation, 'take back control of their devices,' indicates a consumer-level interest, but the underlying technical question is relevant for B2B mobile security. Android's customized kernels often introduce unique security postures. Determining exploitability here is crucial for mobile device management (MDM) and enterprise mobility security solutions. A confirmed vulnerability would significantly impact the security landscape for Android fleets, driving demand for robust mobile endpoint protection. SaaS vendors in this space need to assess and communicate their stance on such kernel-level exploits.

Does the exploit work on Android's Linux kernels?
Can be exploit be used on the relevant affected Linux kernel versions that exist on various Android devices, or is the Linux kernel that Android uses immune from the exploit because of whatever special stuff they may do? Would be interesting to know about since whenever an exploit like this is discovered in the kernel that achieves privilege escalation it would be a very useful tool for people to take back control of their devices and fight against the ARM dystopia.
Developer Debate & Comments
It does not on any of the devices I have tested. But it does not mean they are not affected, just that this specific code does not work for those targets. They might still be vulnerable.
> But it does not mean they are not affected, just that this specific code does not work for those targets the particular exploit contains x86_64 binary code (see https://github.com/V4bel/dirtyfrag/blob/892d9a31d391b7f0fccb333855f6289507186748/exp.c#L43), so can't work verbatim on ARM
[Comment thread on HN about it](https://news.ycombinator.com/item?id=48054201). The Linux kernel used by Android may be hardened to make it not possible (I don't know if Copy Fail was ever possible on Android). But time will tell I suppose.
It shouldn't be. I'm not aware that Android kernels have either loadable kernel modules nor XFRM/RXRPC support, and most definitely not accessible to regular user apps. Android also doesn't really have SUID binaries, so while it potentially could be used to exploit something else to one's advantage, it ain't gonna give you a root shell on Android. The exploit relies on `su` being a SUID binary. The exploit only rewrites `su` to not check password and exploit its existing ability to become root by virtue of being a SUID binary.
Android's SELinux setup blocks weird socket types. Additionally Android has no suid binaries.

Seems once a host as run the exploit, it won't stop until rebooted. ``` [tdockendorf@OMIT dirtyfrag]$ ./exp dirtyfrag: failed (rc=1) ``` On mitigated host that hadn't been exploited yet.
Correct - i can confirm that, exploited hosts / tests the mitigation (removing/disabling esp4 esp6 and rxrpc) do need a reboot. Just removing the kernel modules without rebooting does not affect al...
Can you try to drop the page cache after the exploit? This should work without a reboot. ``` sudo echo 3 > /prox/sys/vm/drop_caches ```

That kernel is way too old for that. The bug was introduced in a commit from 2017-01-17, your kernel is from 2013.
It's true that 3.10 was released in 2013 (with LTS thru 2017 I think). That said, Red Hat does a lot of back porting into their EL kernels and 3.10.0-1160 was released in 2020 (still old) with end ...
They usually backport security fixes, not entire features. If it's not essential, it's not backported. I can't see why they would have backported that stuff unless it was breaking something else im...

It's as bad as getting root in a container. You'd still need to chain a container escape exploit. They tend to be easier to pull off with root access, but without a current container escape exploit...
Depends on the setup. Same as with copy.fail, you could use this to corrupt the kernel memory view of any file that can be opened. The NVIDIA container integration for CUDA for instance makes some ...

The kernel is Ubuntu and user space is Debian
Maybe we should evaluate the unprivileged LXC case: if it's blocked by seccomp/AppArmor, the risk is likely low.
