Description OSIDB Bzimport 2025-12-08 07:06:59 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ntfs3: pretend $Extend records as regular files

Since commit af153bb63a33 ("vfs: catch invalid modes in may_open()")
requires any inode be one of S_IFDIR/S_IFLNK/S_IFREG/S_IFCHR/S_IFBLK/
S_IFIFO/S_IFSOCK type, use S_IFREG for $Extend records.
