I don't understand, the picture of devkit has something to do with the kernel exploit?
Perhaps he meant that someone had written some 6.51 string on twitter, but we should not forget that it was a random string that was not confirmed by anyone trusted.
for example, I will write here:
r123456 / release_branches / release_06.510 Mar 19 2019 99:88:77 amd64
r133333 / release_branches / release_06.690 Mar 20 2019 69:69:69 amd64
does that mean it's a kernel exploit?
The SCE page says:
A hacker Tweeted a 5.55 kernel string.
A hacker Tweeted a 6.20 kernel string.
A hacker Tweeted a 6.50 kernel string.
which is right, there is not this:
A random kid Tweeted a random 6.51 kernel string.
A animal Tweeted a random 6.51 kernel string.
it is important to read the facts
So, as I thought, no official confirmation kernel exploit for 6.51 ... which does not confirm anything, but nothing refutes ... so wait
we have a lot of time.
