Title
smb: client: fix double put of @cfile in smb2_rename_path()
Summary
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix double put of @cfile in smb2_rename_path() If smb2_set_path_attr() is called with a valid @cfile and returned -EINVAL, we need to call cifs_get_writable_path() again as the reference of @cfile was already dropped by previous smb2_compound_op() call.
Severity

This is remote-peer data driving kernel memory management on the client.\nAC:L - The server simply answers a compounded CREATE+SET_INFO(rename) with STATUS_INVALID_PARAMETER \u2014 deterministic, no race to win, no memory-layout guessing, and leases are enabled by default. The same condition even arises reliably against benign servers for hardlinked files, which is precisely the case the introducing commit describes.\nPR:N - The attacker is the remote SMB endpoint and needs no account, credentials, or privileges on the victim client; the client initiates and authenticates the connection itself and then processes the poisoned status code during a routine rename of an open file.\nUI:N - No human action is required \u2014 renames of files held open on an SMB mount are ordinary automated activity (backup/sync daemons, log rotation, package and build tooling), so the attacker-controlled server merely waits for one and replies with STATUS_INVALID_PARAMETER.\nS:U - The corruption is confined to the client kernel\u0027s own heap and security authority; no VM, hypervisor, or IOMMU boundary is crossed.\nC:H - The premature free leaves file-\u003eprivate_data dangling and smb2_compound_op() kstrdup()s cfile-\u003esymlink_target out of freed memory into data returned to userspace, and a reclaimed cifsFileInfo yields a general arbitrary kernel-heap read primitive.\nI:H - The freed cifsFileInfo contains three list_heads whose later list_del gives an arbitrary write, plus four work_struct/delayed_work members with func pointers that can be queued after slab reclaim for control-flow hijack, making this a full write/code-execution primitive.\nA:H - The refcount underflow frees the handle while the fd remains open, so the next read/write or close on that fd hits freed memory, causing list corruption, a double free, and a kernel oops/panic."
