No network path exists to fs/hfsplus.\nAC:L - The attacker fully authors the HFS+ attributes b-tree — the unicode key length, the xattr names, and the number of attribute records — and `hfsplus_uni2asc()` deterministically leaves `strbuf[xattr_name_len]` unwritten; the kmalloc-1k slab can be groomed so that byte is non-zero, making the `-E2BIG` path and the negative-`res` shift reliable.\nPR:L - Once the crafted image is mounted (auto-mount of removable media, a kiosk/shared workstation, or an admin-mounted untrusted image), any unprivileged local user can trigger the whole chain with a single `listxattr()` call — no capability is checked on that path (`can_list()` only gates `trusted.` names).\nUI:N - No victim action is required after the image is present — the unprivileged attacker performs the syscall itself, and on systems with automounting the media is mounted without any interactive step.\nS:U - The corruption and disclosure are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `vsnprintf` walks the un-terminated `strbuf` past its 767-byte allocation (out-of-bounds slab read), and the negative-`res` shift leaves never-written regions of the `kvmalloc()`'d `klist` that `copy_to_user()` then hands to userspace, disclosing arbitrary uninitialized kernel heap contents.\nI:H - `strscpy()` returning `-E2BIG` makes `copy_name()` return -7, driving `res` negative and bypassing the `size <` bounds check, so later iterations write attacker-controlled xattr-name bytes at `klist + negative_offset` — a heap buffer underflow with attacker-chosen data and attacker-chosen distance (7 bytes per crafted attribute), a strong write primitive for control-flow hijacking.\nA:H - The out-of-bounds read past the slab object and the out-of-bounds writes before the `kvmalloc()` buffer corrupt adjacent heap state and readily produce a KASAN report, oops, or kernel panic." } ] } ],
