Vulnerability from github – Published: 2024-10-29 03:31 – Updated: 2025-11-04 00:31

Details

In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix uninitialized pointer free in add_inode_ref()

The add_inode_ref() function does not initialize the "name" struct when it is declared. If any of the following calls to "read_one_inode() returns NULL,

dir = read_one_inode(root, parent_objectid);
if (!dir) {
    ret = -ENOENT;
    goto out;
}

inode = read_one_inode(root, inode_objectid);
if (!inode) {
    ret = -EIO;
    goto out;
}

then "name.name" would be freed on "out" before being initialized.

out: ... kfree(name.name);

This issue was reported by Coverity with CID 1526744.

Severity

7.8 (High)

The image can be supplied as an ordinary file and loop-mounted, so no physical device access is needed.\nAC:L - The attacker fully authors the on-disk log tree \u2014 inode ref/extref keys, parent objectids, and name lengths \u2014 so both the NULL `read_one_inode()` return and the stack-slot priming are deterministic; `replay_one_buffer()` deliberately continues past `-ENOENT`, letting the attacker stage a preceding call that leaves a known dangling pointer in the identical stack slot. No unpredictable condition must be won.\nPR:L - Mounting btrfs nominally needs CAP_SYS_ADMIN, but udisks2/`LoopSetup` and desktop/kiosk automount let a basic unprivileged local user get an arbitrary attacker-supplied btrfs image mounted, so real root in the initial namespace is not required.\nUI:N - In the realistic kiosk/workstation deployment, automount (or the attacker\u0027s own udisks2 loop-mount of a file they control) mounts the crafted image without any other user participating, and replay then runs unconditionally \u2014 including for read-only mounts.\nS:U - The corruption is confined to the kernel\u0027s own slab allocator and control flow within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `kfree()` of an uninitialized/stale pointer yields a controlled double free of an attacker-size-selected kmalloc object, which reallocates into a live kernel object and gives a use-after-free read primitive over arbitrary kernel memory.\nI:H - The same double free/UAF over a general-purpose kmalloc slab permits heap grooming, type confusion, and arbitrary kernel write, which is exploitable for control-flow hijack and privilege escalation.\nA:H - In the common case the uninitialized stack value is not a valid slab pointer, so `kfree()` faults in `virt_to_head_page()`/`__free_frozen_pages()` and oopses during mount; the double-free variant trips SLUB corruption BUGs.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
