The developer Codelion (aka @ BBalling1), one of the people behind the feat Webkit Vita release a tool for devs who want to play with the fault.
memtools_vita allows Dump the contents of the modules used by Webkit process, but for this special server CodeLion is required. Provides the readme explains how to do this (in English of course). However, at present, one of the known issues and that this tool does not allow Dump the executable code [data] section only. The ADA software for example do not like it, but it would be sufficient for further investigation and it seems, according to the readme, this section is still possible to dump. A Python now your servers. memtools_vita
