Hi all, long time listener, first time caller. I read the writeup on KindleDrip and KindleBreak which exploited a couple vulnerabilities to get root access on kindles that facilitated their jailbreaks.
I dunno if this is a dumb question, but is it possible that >=5.14.3 firmwares are running vulnerable versions of the linux kernel where there are known privilege escalation exploits?
I'm on my phone right now so I only did a little poking around in the termux app, but I downloaded Kindle_src_5.14.3.0.1_3838590001.tar.gz from the GPL release page, and it appears to include linux kernel version 4.9.77, which is a pretty old release. There are a few big exploits that could get us root access if they haven't been patched.
Maybe I'm just being dumb and the GPL releases aren't all that close to the linux kernel that's actually included in the Kindle firmware, but this seems like a really nice community so I thought I'd ask!
