The goal of this project is to build and provide all possible Volatility3 profiles for the main Linux distributions in x86_64 version only.
This project contains all kernel versions including security updates.

The are two methods to find your profile:
- Use the kernel package name with version and add -dbg, -dbgsym or -debuginfo, depending on the linux distribution;
- Use Linux banners index (banners.json), for example:
grep "Linux version 6.2.0-1007-aws (buildd@lcy02-amd64-106) (x86_64-linux-gnu-gcc-11 (Ubuntu 11.3.0-1ubuntu1~22.04.1) 11.3.0, GNU ld (GNU Binutils for Ubuntu) 2.38) #7~22.04.1-Ubuntu SMP Fri Jul 7 13:49:28 UTC 2023 (Ubuntu 6.2.0-1007.7~22.04.1-aws 6.2.13)" banners.json | jq .symbols_file
"linux-image-unsigned-6.2.0-1007-aws-dbgsym_6.2.0-1007.7~22.04.1_x86_64.json.xz"
Note: the banner is recovered via the volatility3 plugin banners.Banners.
Each of these profiles is packaged as a compressed .json.xz file. You can enable them individually in your Volatility installation by copying it in volatility3/symbols/linux/.
All processors are docker container. Build then with this script:
./make.shCreating a profile for Volatility 3 does not require installing a Linux identical to the sampled machine.
On the analysis machine, download and compile dwarf2json from https://github.com/volatilityfoundation/dwarf2json
# if Go not installed:
apt install golang-go -y
# Downloadind and compiling
git clone https://github.com/volatilityfoundation/dwarf2json.git
cd dwarf2json/
go buildCompiling need Go 1.14 or higher.
To create a profile with dwarf , you must download or install a linux kernel with the debugging symbols of a version strictly equal to that of the sampling.
According to the distributions, the name of the corresponding package is the following:
| Distro | Package name | Repository | Archive repository |
|---|---|---|---|
| Debian | linux-image-$(uname -r)-dbg | main | http://snapshot.debian.org/ |
| Ubuntu | linux-image-$(uname -r)-dbgsym | http://ddebs.ubuntu.com/ | none |
| CentOS | kernel-debuginfo-$(uname -r).rpm | base-debuginfo | https://vault.centos.org/ |
| RedHat | kernel-debuginfo-$(uname -r).rpm | RHEL, RHN | RedHat Netwok (fee) |
| AlmaLinux | kernel-debuginfo-$(uname -r).rpm | baseos-debuginfo | https://repo.almalinux.org/vault/ |
The package can be either installed or unpacked on any OS with 7zip for example.

Debian: if the package is no longer present on the repository, it is possible to go back in time with http://snapshot.debian.org/ . Find and download the package from the home page search engine.
./dwarf2json linux --elf /usr/lib/debug/boot/vmlinux-4.4.0-137-generic > linux-4.4.0.json
cp linux-4.4.0.json <volatility3>/symbols/
In some cases, adding the option --system-map System-map-$(uname -r) may be necessary when creating the profile.
