              "value": "AV:L - The vulnerability is reached only by mounting a crafted HFS+ volume (loop-backed image or removable media) and then issuing ordinary syscalls \u2014 `unlink(2)`/`rmdir(2)` driving `hfsplus_delete_all_attrs` \u2192 `hfs_brec_remove` \u2192 `hfs_bnode_dump`, or `readdir`/`getxattr` driving `__hfs_brec_find`. No remote or network-facing consumer of fs/hfsplus/bnode.c exists.\nAC:L - The out-of-bounds index is taken verbatim from on-disk 16-bit fields the attacker authors \u2014 record offsets returned by `hfs_brec_lenoff()` and the node descriptor\u0027s `num_recs` \u2014 so a single purpose-built image triggers it deterministically on the first unlink. There is no race, timing window, or memory-layout precondition outside the attacker\u0027s control, and the adjacent kmalloc-192 slab contents can be groomed by repeated bnode allocations.\nPR:L - The bare `mount(2)` needs CAP_SYS_ADMIN since hfsplus is FS_REQUIRES_DEV without FS_USERNS_MOUNT, but in the most severe reasonable deployment an unprivileged local user routinely gets an attacker-controlled HFS+ image mounted via udisks2 loop-setup/mount in a desktop session, removable-media automounters on kiosks and embedded systems, or `user`/autofs fstab delegation. Once mounted, the unlink/rmdir/readdir that fires the bug needs no privilege at all.\nUI:N - The attacker performs every step personally \u2014 presents the crafted volume (which the automounter consumes without any human action) and then runs the unlink or rmdir that reaches `hfs_brec_remove()`. No second, victim user has to be induced into any action.\nS:U - The corruption occurs in HFS+ btree node handling inside the kernel and its effects stay within that same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The unvalidated index loads a `struct page *` from out-of-bounds slab memory and `memcpy_from_page()` then copies up to a full page from the arbitrary kernel address that pointer resolves to. That data lands in `fd-\u003ekey` and in catalog/attribute record buffers (bfind.c:222) that are handed straight back to userspace via readdir, getxattr, and listxattr, giving a repeatable arbitrary-kernel-memory disclosure primitive.\nI:H - The identical bogus `struct page *` is used on the write side by `hfs_bnode_write()`, `hfs_bnode_clear()`, `hfs_bnode_copy()`, and `hfs_bnode_move()`, whose `memcpy_to_page()`/`memmove()` deposit attacker-chosen bytes at an arbitrary kernel address. `hfs_brec_remove()` compounds this by passing `data_off - fd-\u003ekeyoffset - size`, which underflows from on-disk u16 values into an enormous length \u2014 an out-of-bounds write suitable for corrupting adjacent kernel objects and hijacking control flow.\nA:H - Dereferencing a garbage `struct page *` faults or corrupts memory in the middle of an unlink while holding the inode lock and the btree mutex, producing an oops that wedges the filesystem and leaks the held locks. On systems with `panic_on_oops` \u2014 standard in appliances, automotive, and embedded builds \u2014 it is an immediate full system panic, and the attacker can repeat it at will."
