ocfs2: dlmfs: fix error handling of user_dlm_destroy_lock
Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: dlmfs: fix error handling of user_dlm_destroy_lock
When user_dlm_destroy_lock failed, it didn't clean up the flags it set
before exit. For USER_LOCK_IN_TEARDOWN, if this function fails because of
lock is still in used, next time when unlink invokes this function, it
will return succeed, and then unlink will remove inode and dentry if lock
is not in used(file closed), but the dlm lock is still linked in dlm lock
resource, then when bast come in, it will trigger a panic due to
user-after-free. See the following panic call trace. To fix this,
USER_LOCK_IN_TEARDOWN should be reverted if fail. And also error should
be returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink
fail.
For the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN,
USER_LOCK_BUSY is also required to be cleared. Even though spin lock is
released in between, but USER_LOCK_IN_TEARDOWN is still set, for
USER_LOCK_BUSY, if before every place that waits on this flag,
USER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow
waits on the busy flag set by user_dlm_destroy_lock(), then we can
simplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails. Fix
user_dlm_cluster_lock() which is the only function not following this.

"value": "AV:L - The bug is triggered via local VFS operations (open/unlink) on the ocfs2_dlmfs filesystem, not by parsing network packets. Although a remote cluster peer\u2019s DLM request can later deliver the BAST that touches the freed object, setting up the corrupt state requires local syscall access.\nAC:L - The attacker fully controls both sides of the trigger sequence: hold the lock open, unlink (fails but leaves USER_LOCK_IN_TEARDOWN set), close, then unlink again so the inode is freed while the DLM lock remains. A conflicting lock request (local recreate/open or peer) reliably produces the BAST on the stale lockres.\nPR:L - dlmfs is a documented userspace DLM API; once an administrator has mounted it and created domain directories (modes/chown are explicitly supported for access control), an unprivileged user with write access can create, open, and unlink lock inodes and hit this path without CAP_SYS_ADMIN.\nUI:N - Exploitation is performed entirely by the attacker\u2019s own open/close/unlink syscalls against dlmfs; no separate victim action is required.\nS:U - This is a same-host kernel UAF enabling privilege escalation within the kernel\u2019s security authority; it does not cross a VM, IOMMU, or other security boundary.\nC:H - The commit documents a use-after-free: after the erroneous successful unlink, the DLM still holds a callback into the freed dlmfs_inode_private/user_lock_res (kmem_cache object), which can be reclaimed and read through the BAST path.\nI:H - The same UAF on a slab-allocated inode-private object is exploitable for heap reuse and arbitrary write/control-flow hijack when a BAST runs against attacker-controlled reclaimed memory.\nA:H - The demonstrated impact is a kernel BUG() in user_dlm_grab_inode_ref during BAST handling that escalates to a full kernel panic, and any UAF can also crash via corrupted freed memory."

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.
