Re: [PATCH] ntfs: Fix validity check for file name attribute

Hi,

I was just scanning through some older vulnerabilities and came across
CVE-2018-12929, CVE-2018-12930, and CVE-2018-12931, which are all still open
according to linuxkernelcves.com (originally reported against 4.15 [1]). I
looked into the commits in fs/ntfs/ from 4.15 onwards to see if they were just
missed, but I can't spot anything there. RedHat claims to have them fixed in
one of their kernels [2].

Which makes me wonder if the issue fixed here is a duplicate of the any of the
above. Is there a reason I can't find any patches for the original issue in
tree, like the issue only introduced in a custom patchset that Ubuntu/RedHat
were using? Is this thing worth it's own CVE if it's no duplicate?

Greetings,

Eike
