The race partner (SMB session teardown) is local mount/umount or per-uid session teardown activity.\nAC:L - The attacker controls both sides \u2014 an unprivileged read loop on the world-readable proc file, plus session teardown they can force repeatedly on multiuser/autofs CIFS mounts \u2014 and `__cifs_put_smb_ses()` holds the SES_EXITING window open across a blocking SMB LOGOFF round-trip, making the window wide and reliably hit.\nPR:L - `/proc/fs/cifs/Stats` is created mode 0644 in the global, non-namespaced procfs, so any unprivileged local user \u2014 including one inside a container with `/proc` mounted \u2014 can trigger the vulnerable read path. No capability, and no CIFS mount ownership, is required.\nUI:N - No victim action is needed: the attacker\u0027s own access to a multiuser mount creates and tears down per-fsuid SMB sessions, and ordinary background CIFS mount/reconnect/prune activity supplies the teardown otherwise.\nS:U - The use-after-free occurs in kernel memory and its effects stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Contents of the freed `cifs_tcon` \u2014 including `tree_name` printed with `%s`, which reads until a NUL and can run past the freed object \u2014 are copied into the seq_file buffer returned to the unprivileged reader, yielding a kernel heap disclosure that can be aimed at reallocated sensitive data via heap grooming.\nI:H - A use-after-free of this class gives the attacker influence over the freed slab object\u0027s contents, letting dereferenced pointers (`server-\u003eops-\u003eprint_stats`, tcon list links) be steered by heap spraying into a control-flow/corruption primitive rather than a mere stale read.\nA:H - The confirmed sibling bug produced a general protection fault on slab poison in exactly this traversal, and the oops happens while the global `cifs_tcp_ses_lock` spinlock is held, hanging all subsequent CIFS operations system-wide on top of killing the faulting task."

The race partner (SMB session teardown) is local mount/umount or per-uid session teardown activity.\\nAC:L - The attacker controls both sides \\u2014 an unprivileged read loop on the world-readable proc file, plus session teardown they can force repeatedly on multiuser/autofs CIFS mounts \\u2014 and `__cifs_put_smb_ses()` holds the SES_EXITING window open across a blocking SMB LOGOFF round-trip, making the window wide and reliably hit.\\nPR:L - `/proc/fs/cifs/Stats` is created mode 0644 in the global, non-namespaced procfs, so any unprivileged local user \\u2014 including one inside a container with `/proc` mounted \\u2014 can trigger the vulnerable read path. No capability, and no CIFS mount ownership, is required.\\nUI:N - No victim action is needed: the attacker\u0027s own access to a multiuser mount creates and tears down per-fsuid SMB sessions, and ordinary background CIFS mount/reconnect/prune activity supplies the teardown otherwise.\\nS:U - The use-after-free occurs in kernel memory and its effects stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\\nC:H - Contents of the freed `cifs_tcon` \\u2014 including `tree_name` printed with `%s`, which reads until a NUL and can run past the freed object \\u2014 are copied into the seq_file buffer returned to the unprivileged reader, yielding a kernel heap disclosure that can be aimed at reallocated sensitive data via heap grooming.\\nI:H - A use-after-free of this class gives the attacker influence over the freed slab object\u0027s contents, letting dereferenced pointers (`server-\u003eops-\u003eprint_stats`, tcon list links) be steered by heap spraying into a control-flow/corruption primitive rather than a mere stale read.\\nA:H - The confirmed sibling bug produced a general protection fault on slab poison in exactly this traversal,
