Technical Positioning
Exploitability on Ubuntu 26.04
SaaS Insight & Market Implications
This issue confirms `dirtyfrag` exploit functionality on Ubuntu 26.04 with kernel 7.0.0-15-generic. This direct confirmation is valuable for security practitioners and SaaS vendors. It establishes a clear target environment for vulnerability assessment and mitigation efforts. The market implication is that organizations running this specific Ubuntu version are directly exposed. Security SaaS providers must update their threat intelligence and detection capabilities to account for this confirmed vulnerability, offering specific guidance and protection for Ubuntu 26.04 deployments. This data point informs risk prioritization and resource allocation for security product development.

Developer Debate & Comments
Yeah. I could touch a file that got root permissions.
yes here too mitigation : sh -c "printf 'install esp4 /bin/false\ninstall esp6 /bin/false\ninstall rxrpc /bin/false\n' > /etc/modprobe.d/dirtyfrag.conf; rmmod esp4 esp6 rxrpc 2>/dev/null; true" works on all my servers, including ubuntu 26.04, after a reboot

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 ```

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.

[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...

Exploitability and compilation on EL7 (CentOS 7.9)

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...

Container escape capability of the vulnerability

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 ...
I have tested it on GKE and ACK clusters. All failed. On ACK default node image: user.max_user_namespaces is set 0, so unprivileged user can't use CLONE_NEWUSER unshare. On GKE default node image (...

No surprise.. proxmox kernels are based heavily on Debian. Just in case you had not already done this, I have emailed proxmox security team to alert them. Also posted here since there is no point i...
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.
