This exploit uses the pokemon exploit of the dirtycow vulnerability as a base and automatically generates a new passwd line. The user will be prompted for the new password when the binary is run.

May 18, 2024 - “Run and pwn”, as the documentation says, with an exploit that generates a new password hash on the fly and modifies /etc/passwd automatically. Although it’s a patched Linux kernel bug, attackers continue to use it in their activities.

"A race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write (COW) feature to write to a read-only memory mapping, as exploited in the ...

April 1, 2026 - Dirty Cow was one of the first security issues transparently fixed in Ubuntu by the Canonical Live Patch service. It has been demonstrated that the vulnerability can be utilized to root any Android device before Android version 7 (Nougat). The vulnerability has existed in the Linux kernel since version 2.6.22 released in September 2007, and there is information about it being actively exploited ...

An exploit using this technique has been found in the wild from an HTTP packet capture according to Phil Oester. This FAQ provides answers to some of the most frequently asked questions regarding the Dirty COW vulnerability.

May 10, 2019 - Note: I was able to re-exploit the system after the cleanup process was completed.

November 28, 2016 - // // This exploit uses the pokemon exploit of the dirtycow vulnerability // as a base and automatically generates a new passwd line. // The user will be prompted for the new password when the binary is run.

June 24, 2020 - First of all thank you for this amazing tool, I want a small correction in an exploit download page suggested by linux-exploit-suggester for Dirty Cow 2 https://www.exploit-db.com/exploits/40847.cp...

In Dirty COW, an attacker could exploit a race condition in the COW mechanism to gain write access to read-only memory mappings. By doing so, they could alter sensitive data or execute arbitrary code within the kernel space, potentially achieving privilege escalation.

Dirty COW was a vulnerability in the Linux kernel. It allowed processes to write to read-only files. This exploit made use of a race condition that lived inside the kernel functions which handle the copy-on-write (COW) feature of memory mappings. An example use case includes over-writing a ...

March 27, 2024 - “Run and pwn”, as the documentation says, with an exploit that generates a new password hash on the fly and modifies /etc/passwd automatically. Although it’s a patched Linux kernel bug, attackers continue to use it in their activities.

This exploit enables an unauthenticated attacker to modify system files, deploy key loggers and remotely read data that has been collected during telepresence sessions or video conferences.

October 22, 2024 - Learn 7 essential strategies to protect against the Dirty Cow exploit, from kernel-level integrity monitoring to automated patching and real-time detection with eBPF.

Because using /proc/self/mem makes the kernel use code that is intended to allow a process to access the memory of another process, and that is this code that contains the vulnerability. Even though here we access the memory of our own process, we need to do it in a way that allows us to exploit the vulnerable kernel code. In a second thread, repeat the following code, such that it runs concurrently to the code in point 2.

November 17, 2025 - This flaw is a widespread vulnerability and spans Red Hat Enterprise Linux versions 5, 6, and 7. Technical details about the vulnerability and how to address it can be found at: Kernel Local Privilege Escalation "Dirty COW" - CVE-2016-5195. In order to be successful, an attacker must already have access to a server before they can exploit the vulnerability.
