Title
btrfs: fix uninitialized pointer free in add_inode_ref()
Summary
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.

"value": "AV:L - The bug is reached only through btrfs log-tree replay during `open_ctree()`/`btrfs_replay_log()`, i.e. by mounting an attacker-crafted filesystem image, which requires local access to the system. 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. Either way the kernel panics."
