I don't remember there being a memory overflow kernel mode exploit. They mostly relied on unchecked k1 values iirc.
To find kernel exploits, we need a better understanding of the firmware. With the PSP, it included reversing portions of the firmware to look for vulnerabilities. At current, no one has released any tools to decrypt the firmware. So, we are a long long way from a CFW, if one is even possible on the Vita. Also, no kernel mode == no flash0 access.
Sony long ago found a way to counter such flash rewrites: encrypting and signing. The 1.50 OFW was the last to not include these security measures completely iirc.
So, before you get your hopes up: no CFW, not for some time at least.
