Patch Levels
Below is version information for branches and devices for you to judge your device's security upon.
A note on ROM security¶
There are five parts that you can use to determine the general security of a ROM:
- the version of Android itself, newer versions have more security features/hardening
- the ASB patch level, these are essential security patches
- the Pixel ASB patch level, these are recommended security patches
- the vendor ASB patch level, see Qualcomm
- and lastly the Linux kernel version
- GrapheneOS strictly only supports devices that have all parts updated.
- CalyxOS, with the exception of the Pixel 2 and Mi A2, only supports devices that have all parts updated.
- LineageOS can help with 1, 2, 3, and usually 5, but if a device is out of support by its manufacturer it cannot help with 4.
- DivestOS, being Lineage based helps with 1, 2, 3, can minimize 4 via the deblobber, and improve 5 significantly using the CVE auto-patcher.
- LineageOS (and derivatives) notably only apply Pixel ASB's to the most recent branch.
- Any of the above ROMs will be a dramatic improvement for any device that is no longer receiving support from its manufacturer.
- Replicant 6.0 is based on the LineageOS-13.0 branch and is behind on all parts.
