high Tenable Self-Hosted Container Security Plugin ID 469889

Description

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: fs/ntfs3: fix out-of-bounds read of
INDEX_ROOT in reparse/objid init ntfs_reparse_init() and ntfs_objid_init() parse the index root of the
$Extend/$Reparse and $Extend/$ObjId metafiles (the INDEX_ROOT attributes named $R and $O). They read its
type and rule fields through resident_data(), which does not check that the resident attribute is large
enough to hold them. mi_enum_attr() accepts a resident attribute with data_off == asize and data_size ==
0. For such an attribute placed last in its MFT record, resident_data() returns a pointer to the end of
the record_size buffer, so reading root->type / root->rule reads past the allocation. Use
resident_data_ex(attr, sizeof(struct INDEX_ROOT)) and bail out when it returns NULL, as
ntfs_security_init() already does for $SDH / $SII. The attribute is only parsed while mounting a crafted
image, so this needs CAP_SYS_ADMIN. BUG: KASAN: slab-out-of-bounds in ntfs_reparse_init
(fs/ntfs3/fsntfs.c:2306) Read of size 4 at addr ffff88801219dc00 by task mount ntfs_reparse_init
(fs/ntfs3/fsntfs.c:2306) ntfs_fill_super (fs/ntfs3/super.c:1604) get_tree_bdev_flags (fs/super.c:1703)
vfs_get_tree (fs/super.c:1758) path_mount (fs/namespace.c:4131) __x64_sys_mount (fs/namespace.c:4360)
(CVE-2026-89785)
