Title
um: Add winch to winch_handlers before registering winch IRQ
Summary
In the Linux kernel, the following vulnerability has been resolved: um: Add winch to winch_handlers before registering winch IRQ Registering a winch IRQ is racy, an interrupt may occur before the winch is added to the winch_handlers list. If that happens, register_winch_irq() adds to that list a winch that is scheduled to be (or has already been) freed, causing a panic later in winch_cleanup(). Avoid the race by adding the winch to the winch_handlers list before registering the IRQ, and rolling back if um_request_irq() fails.

Although the `con=port:` telnet channel type can have its setup triggered by an incoming connection, the standard and reliable reach is local.\nAC:L - The attacker creates and repeats the race themselves \u2014 closing and reopening the line clears `line-\u003esigio` and re-runs `register_winch_irq()`, so the tiny window between `um_request_irq()` and `list_add()` can be attacked in an unbounded retry loop. Once the early interrupt lands, the freed object stays linked in the global `winch_handlers` list deterministically, and the later dereference is delayed long enough for reliable heap grooming.\nPR:L - No capability or credential check exists anywhere on the path from `open()` through `line_open()` \u2192 `line_activate()` \u2192 `register_winch_irq()`; only device-node permissions gate it, and a plain unprivileged guest user is sufficient both to open a console/serial line and to spray the `kmalloc-96` slab that reclaims the freed `struct winch`.\nUI:N - Winch registration happens automatically when a configured console line is first opened (including at boot), and the attacker can drive that open themselves. No action by any other user is required.\nS:U - The corruption and its impact are confined to the UML kernel\u0027s own memory and the process it already fully controls, which is standard in-kernel privilege escalation. No hypervisor, IOMMU, or sandbox authority boundary is crossed by the vulnerable component.\nC:H - This is a use-after-free on a small, easily reclaimed slab object; the later walk of `winch_handlers` calls `tty_port_tty_get(winch-\u003eport)` on an attacker-controlled pointer, giving an arbitrary-dereference read primitive usable to disclose kernel memory.\nI:H - The stale `list_add()` writes two pointers into freed (reclaimable) memory, and the later `free_winch()` performs `free_stack(winch-\u003estack, 0)` on an attacker-controlled address plus a double `kfree()` and `os_kill_process(winch-\u003epid, 1)`, yielding write/free primitives suitable for control-flow hijack.\nA:H - The commit itself states the dangling list entry causes a panic in `winch_cleanup()`, and any use-after-free of this kind reliably produces an oops or kernel panic in the UML instance."

Although the `con=port:` telnet channel type can have its setup triggered by an incoming connection, the standard and reliable reach is local.\nAC:L - The attacker creates and repeats the race themselves \u2014 closing and reopening the line clears `line-\u003esigio` and re-runs `register_winch_irq()`, so the tiny window between `um_request_irq()` and `list_add()` can be attacked in an unbounded retry loop. Once the early interrupt lands, the freed object stays linked in the global `winch_handlers` list deterministically, and the later dereference is delayed long enough for reliable heap grooming.\nPR:L - No capability or credential check exists anywhere on the path from `open()` through `line_open()` \u2192 `line_activate()` \u2192 `register_winch_irq()`; only device-node permissions gate it, and a plain unprivileged guest user is sufficient both to open a console/serial line and to spray the `kmalloc-96` slab that reclaims the freed `struct winch`.\nUI:N - Winch registration happens automatically when a configured console line is first opened (including at boot), and the attacker can drive that open themselves. No action by any other user is required.\nS:U - The corruption and its impact are confined to the UML kernel\u0027s own memory and the process it already fully controls, which is standard in-kernel privilege escalation. No hypervisor, IOMMU, or sandbox authority boundary is crossed by the vulnerable component.\nC:H - This is a use-after-free on a small, easily reclaimed slab object; the later walk of `winch_handlers` calls `tty_port_tty_get(winch-\u003eport)` on an attacker-controlled pointer, giving an arbitrary-dereference read primitive usable to disclose kernel memory.\nI:H - The stale `list_add()` writes two pointers into freed (reclaimable) memory, and the later `free_winch()` performs `free_stack(winch-\u003estack, 0)` on an attacker-controlled address plus a double `kfree()` and `os_kill_process(winch-\u003epid, 1)`, yielding write/free primitives suitable for control-flow hijack.\nA:H - The commit itself states the dangling list entry causes a panic in `winch_cleanup()`, and any use-after-free of this kind reliably produces an oops or kernel panic in the UML instance."
