Hacks When can I jailbreak my device?

Hi everyone! I am thinking about jailbreaking my Kindle Oasis 9th gen. Unfortunately, it seems that I have just missed a great opportunity to do this because my device has the latest firmware already patched against the jailbreak-enabling bug disclosed earlier this year. Is there any estimate of roughly when another vulnerability can be found in the current latest firmware to enable jailbreaking, as per your experience?

Thank you! :2thumbsup
