Changelogs should be written a bit more careful then :)

Note, that commit was backported to 5.19.2, so 6.0 is not correct...

I'll go update the cve and push out a json update to cve.org with this
information, thanks for letting us know!

Also, this commit was backported to the older kernels, so this is going
to look strange, here's the new text:

+       Issue introduced in 6.0 with commit 7b0a0e3c3a88 and fixed in 4.19.309 with commit d38d31bbbb9d
+       Issue introduced in 6.0 with commit 7b0a0e3c3a88 and fixed in 5.4.271 with commit 0cfbb26ee5e7

+       Issue introduced in 6.0 with commit 7b0a0e3c3a88 and fixed in 5.15.151 with commit 063715c33b4c

+       Issue introduced in 6.0 with commit 7b0a0e3c3a88 and fixed in 6.8 with commit f78c1375339a

Hopefully people's json parsers can handle that well :)

thanks,
