Those bugs might have security implications, but there's no way to know that, unless someone specifically spends time to assess them in that regard. Requesting CVEs for those bugs is a way to get the fixes into distro kernels (even though that doesn't always work promptly [1] :). [1] https://www.openwall.com/lists/oss-security/2018/10/30/2Note, I am scraping the logs for anything that says it is fixed due do a syzbot find or report and backporting them to the stable kernel branches. So those distros that do follow the LTS/stable kernel releases do get these fixes.All of the fixes, Greg?
All of the ones that say they are found by the syzbot, yes. If I have missed any, please let me know, I am only human.
You'd also need to explain very easy to find examples like this: https://www.spinics.net/lists/stable/msg317698.html of random LTS kernels not receiving security fixes. This particular issue was public since April (which is when we backported fixes for it to 4.4/4.14). It's now 4 months later and your 4.4 6-year "supported" LTS kernel still doesn't contain the fixes.
I don't track CVEs nor care about them at all, and rely on others who depend on those older kernels to provide complex backports as they can test them the best. Nothing new at all, it's always been that way. If you know of specific fixes that I have missed, I am glad to accept backports. Right now we are averaging about 22 patches a day in the latest stable release, and 19 in the latest LTS release. That's a tiny 5.5% of the number of patches that are being developed and merged upstream, which means that we know we are missing stuff and we rely on people to point out where we have done so. We take patches from all distros and companies and users where they notice that we have missed things, I would love to take anything that you have noticed that I missed. thanks! greg k-h
