Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: fs: hfsplus: remove WARN_ON() from hfsplus_cat_{read,write}_inode() syzbot is hitting WARN_ON() in hfsplus_cat_{read,write}_inode(), for crafted filesystem image can contain bogus length. There conditions are not kernel bugs that can justify kernel to panic.

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\u0027s 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-\u003epage[]` 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 \u2014 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."
