I= =20 looked into the commits in fs/ntfs/ from 4.15 onwards to see if they were j= ust=20 missed, but I can't spot anything there. RedHat claims to have them fixed i= n=20 one of their kernels [2]. Which makes me wonder if the issue fixed here is a duplicate of the any of = the=20 above. Is there a reason I can't find any patches for the original issue in= =20 tree, like the issue only introduced in a custom patchset that Ubuntu/RedHa= t=20 were using? Is this thing worth it's own CVE if it's no duplicate?
