Title
btrfs: fix uninitialized pointer free on read_alloc_one_name() error
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix uninitialized pointer free on read_alloc_one_name() error
The function read_alloc_one_name() does not initialize the name field of
the passed fscrypt_str struct if kmalloc fails to allocate the
corresponding buffer. Thus, it is not guaranteed that
fscrypt_str.name is initialized when freeing it.
This is a follow-up to the linked patch that fixes the remaining
instances of the bug introduced by commit e43eec81c516 ("btrfs: use
struct qstr instead of name and namelen pairs").

There is no remote or adjacent-network path into tree-log replay.\nAC:L - The attacker supplies the image, so log replay is guaranteed to run and can be padded with thousands of dir-index entries, each producing another `kmalloc(GFP_NOFS)` attempt; the required allocation failure is induced by attacker-generated memory pressure (userspace ballooning, or a memcg-constrained mount context), which is within the attacker\u0027s influence rather than beyond it.\nPR:L - In the most severe realistic deployment \u2014 desktops and kiosks running udisks2/removable-media automount, which supports btrfs \u2014 an unprivileged local user mounts an attacker-prepared btrfs volume with a dirty log without holding root, and the concurrent memory-pressure side needs no privileges at all.\nUI:N - The attacker performs the triggering mount themselves via automount of attacker-controlled removable media or a mount helper; no separate victim has to open a file or take any action.\nS:U - The corruption occurs in kernel slab memory during mount and stays entirely within the kernel\u0027s own security authority, with no crossing of a hypervisor, IOMMU, or sandbox boundary.\nC:H - `kfree()` on an uninitialized stack value can release a still-live slab object whose stale pointer was left by earlier frames in the same mount call chain, yielding a use-after-free that can be reallocated with attacker-chosen data and read back, exposing arbitrary kernel memory.\nI:H - The arbitrary/premature free gives a classic heap-corruption primitive \u2014 reclaiming the freed object with a sprayed structure permits attacker-controlled writes into kernel objects and potential control-flow hijack.\nA:H - Freeing a wild pointer typically faults inside the allocator or trips slab consistency checks, and the resulting use-after-free corrupts kernel state during mount, producing an oops or panic."

There is no remote or adjacent-network path into tree-log replay.\nAC:L - The attacker supplies the image, so log replay is guaranteed to run and can be padded with thousands of dir-index entries, each producing another `kmalloc(GFP_NOFS)` attempt; the required allocation failure is induced by attacker-generated memory pressure (userspace ballooning, or a memcg-constrained mount context), which is within the attacker\u0027s influence rather than beyond it.\nPR:L - In the most severe realistic deployment \u2014 desktops and kiosks running udisks2/removable-media automount, which supports btrfs \u2014 an unprivileged local user mounts an attacker-prepared btrfs volume with a dirty log without holding root, and the concurrent memory-pressure side needs no privileges at all.\nUI:N - The attacker performs the triggering mount themselves via automount of attacker-controlled removable media or a mount helper; no separate victim has to open a file or take any action.\nS:U - The corruption occurs in kernel slab memory during mount and stays entirely within the kernel\u0027s own security authority, with no crossing of a hypervisor, IOMMU, or sandbox boundary.\nC:H - `kfree()` on an uninitialized stack value can release a still-live slab object whose stale pointer was left by earlier frames in the same mount call chain, yielding a use-after-free that can be reallocated with attacker-chosen data and read back, exposing arbitrary kernel memory.\nI:H - The arbitrary/premature free gives a classic heap-corruption primitive \u2014 reclaiming the freed object with a sprayed structure permits attacker-controlled writes into kernel objects and potential control-flow hijack.\nA:H - Freeing a wild pointer typically faults inside the allocator or trips slab consistency checks, and the resulting use-after-free corrupts kernel state during mount, producing an oops or panic."
