There is no network-facing path into the hfsplus catalog btree code.\nAC:L - The attacker fully authors the on-disk image, so `fd->entrylength` and `fd->entryoffset` are deterministic attacker-chosen u16 values from the record-offset table; no race, timing window, or uncontrollable memory layout is needed to reach the failed sanity check and the subsequent unbounded `hfs_bnode_read()`/`hfs_bnode_write()`.\nPR:L - Only ordinary local user access is required in the realistic scenario: an unprivileged logged-in user inserts an HFS+-formatted USB stick or SD card that udisks2/systemd automounts, and post-mount `hfsplus_cat_write_inode()` fires from normal writeback with no further privilege. This matches the scoring of the sibling fix CVE-2023-54130.\nUI:N - The attacker performs the mount themselves (or triggers automount by inserting their own media) and the write path is then reached automatically via inode writeback; no separate victim action is required.\nS:U - The out-of-bounds access and resulting corruption stay within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Continuing past the failed length check makes `hfs_bnode_read()` index past `node->page[]` and dereference an adjacent-heap value as a `struct page *`, copying arbitrary kernel memory into the catalog entry, which is then exposed to userspace through `i_size`, uid/gid/mode, and `init_special_inode()` rdev.\nI:H - `hfsplus_cat_write_inode()` performs `hfs_bnode_write()` of a full 88/248-byte record at the unvalidated offset, giving an out-of-bounds kernel write (plus `set_page_dirty()` on a bogus pointer) with partially attacker-influenced contents — a corruption primitive usable for control-flow hijack, and at minimum silent metadata corruption.\nA:H - The `WARN_ON()` itself panics the kernel on `panic_on_warn=1` systems, and the wild `struct page *` dereference that follows reliably oopses or panics the kernel." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
