There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - In the Linux kernel, the following vulnerability has been resolved: ntfs: bound $AttrDef table walk to the
    loaded table size ntfs_attr_find_in_attrdef() walks the in-memory $AttrDef table, but the loop condition
    bounds only the start of each entry, not the whole entry: for (ad = vol->attrdef; (u8 *)ad - (u8
    *)vol->attrdef < vol->attrdef_size && ad->type; ++ad) struct attr_def is 160 bytes; the guard reads
    ad->type at offset 128 and the loop body reads further fields. vol->attrdef is kvzalloc(i_size), where
    i_size is the on-disk $AttrDef data size, checked in load_and_init_attrdef() only as 0 < i_size <=
    0x7fffffff. A volume whose $AttrDef data size is smaller than one entry (e.g. 120 bytes) makes the read of
    ad->type run past the allocation. Creating a file reaches this through ntfs_attr_size_bounds_check() and
    reads out of bounds: BUG: KASAN: slab-out-of-bounds in ntfs_attr_find_in_attrdef+0x66/0xa0 Read of size 4
    at addr ffff888005833280 by task init/1 ntfs_attr_find_in_attrdef ntfs_attr_size_bounds_check
    ntfs_attr_can_be_non_resident ntfs_attr_add Require the whole entry to lie within attrdef_size in the loop
    guard, and reject at mount a $AttrDef too small to hold one attr_def entry. (CVE-2026-98136)
