  "details": "## Summary\n\n`Sender::send` in `src/lib.rs` contains an `unsafe` block in the `DISCONNECTED` arm that transmutes a **raw pointer** (`*mut Producer\u003cT\u003e`) into the bytes of a **value-level** `Consumer\u003cT\u003e`. The author\u0027s intent, visible in the surrounding comment at lines 386-390, was a value transmute. The shipped code is one level of indirection off.\n\nThe resulting `Consumer\u003cT\u003e` has its internal `Arc::ptr` set to the address of the `producer` field on the `Sender`, not the real `ArcInner\u003cBuffer\u003cT\u003e\u003e`. Every subsequent `consumer.try_pop()` walks `Buffer\u003cT\u003e` fields at offsets that lie inside the `Sender\u003cT\u003e` struct (over `send_new`, `inner`) and adjacent memory, an out-of-bounds read. When the fake `Consumer\u003cT\u003e` is dropped at the end of the `unsafe` block, its `Drop` calls `Arc::drop_in_place` on a non-`ArcInner` address: it decrements bytes that the type system treats as `strong_count: AtomicUsize` but that are actually the real `Arc::ptr` value of the `Sender`, and at zero count it calls `dealloc(Layout::for_value(...))` on an address the allocator never returned.\n\nReachable from 100% safe Rust through the canonical channel pattern: a `tx.send(msg)` that races with `rx.drop()`. This is consistent with the SIGSEGV that issue #3 reports in your own test suite.\n\n## Affected code (0.2.0, master at `23a9ce7`)\n\n```rust\n// src/lib.rs:384-401\nDISCONNECTED =\u003e {\n    self.inner.counter.store (DISCONNECTED, Ordering::SeqCst);\n    // We want to guarantee if a message was not received that we get it\n    // back; since spsc::{Producer,Consumer} have the same\n    // internal representation (as a singleton struct containing Arc\n    // \u003cBuffer \u003cT\u003e\u003e), we can safely transmute the producer in order to\n    // pop the message back if it was orphaned.\n    unsafe {\n      let consumer : spsc::Consumer \u003cT\u003e\n        = std::mem::transmute (self.producer.get());     // \u003c-- POINTER, not value\n      let first    = consumer.try_pop();\n      let second   = consumer.try_pop();\n      assert!(second.is_none());                          // \u003c-- line 396; smoking-gun assert\n      if let Some(t) = first {\n        return Err (SendError (t))\n      }\n    }\n},\nself.producer is UnsafeCell\u003cspsc::Producer\u003cT\u003e\u003e (line 29). UnsafeCell::\u003cX\u003e::get(\u0026self) returns *mut X, a raw pointer, 8 bytes on 64-bit. The signature of transmute is transmute::\u003cSrc, Dst\u003e(src: Src) -\u003e Dst, so the call expands to transmute::\u003c*mut spsc::Producer\u003cT\u003e, spsc::Consumer\u003cT\u003e\u003e(self.producer.get()). 8 bytes of pointer are reinterpreted as the bytes of a Consumer\u003cT\u003e.\n\nIn bounded-spsc-queue-0.4.0, both Producer\u003cT\u003e and Consumer\u003cT\u003e are newtypes around Arc\u003cBuffer\u003cT\u003e\u003e, one pointer wide. The destination value therefore has Arc::ptr == \u0026mut Producer\u003cT\u003e as *const ArcInner\u003cBuffer\u003cT\u003e\u003e. To be a valid Arc\u003cBuffer\u003cT\u003e\u003e, that pointer must point to ArcInner { strong: AtomicUsize, weak: AtomicUsize, data: Buffer\u003cT\u003e }, but it actually points to the start of Sender\u003cT\u003e (the producer field). The first 8 bytes there hold the real Arc::ptr. The fake Arc reads those bytes as strong_count. The fake try_pop() then reads Buffer\u003cT\u003e head/tail/data slots starting at offset 16 inside the Sender\u003cT\u003e, that is, inside the send_new and inner fields.\n\nThe author\u0027s intent (per the comment at lines 386-390) was a value-level transmute:\n\nlet producer_val: spsc::Producer\u003cT\u003e = std::ptr::read(self.producer.get());\nlet consumer    : spsc::Consumer\u003cT\u003e = std::mem::transmute(producer_val);\nwhich is layout-sound iff Producer\u003cT\u003e and Consumer\u003cT\u003e have identical layouts (they do, both are single-Arc newtypes). The shipped code is one indirection off.\n\nReachability\nThe branch is not reachable single-threaded. Receiver::drop (line 332) stores connected = false before setting counter = DISCONNECTED; Sender::send (line 359) early-returns on connected == false. The trigger is a TOCTOU race:\n\nSender\u0027s self.inner.connected.load(SeqCst) reads true.\nReceiver-drop runs: stores connected = false and counter.compare_exchange(_, DISCONNECTED, SeqCst, SeqCst).\nSender\u0027s self.inner.counter.fetch_add(1, SeqCst) (line 379) sees DISCONNECTED and enters the unsafe block.\nUnder heavy contention this reproduces ~3/10 trials in release mode.\n\nProof of concept (race shape)\n// Cargo.toml: unbounded-spsc = \"0.2\"\nuse std::thread;\nuse unbounded_spsc::channel;\n\nfn main() {\n    for trial in 0..500 {\n        let (tx, rx) = channel::\u003cBox\u003cu64\u003e\u003e();\n        let started = std::sync::Arc::new(\n            std::sync::atomic::AtomicBool::new(false));\n        let s = started.clone();\n        let h = thread::spawn(move || {\n            s.store(true, std::sync::atomic::Ordering::SeqCst);\n            for _ in 0..10_000 {\n                let _ = tx.send(Box::new(0xDEAD_BEEF));\n            }\n        });\n        while !started.load(std::sync::atomic::Ordering::SeqCst) {\n            std::hint::spin_loop();\n        }\n        drop(rx);\n        let _ = h.join();\n        eprintln!(\"trial {trial} ok\");\n    }\n}\nObserved:\n\nRelease-mode (no sanitizer): Segmentation fault (core dumped) reliably within a few trials. The non-segfaulting trials are masked by the separate send_new.send(new_consumer).unwrap() panic, see Secondary defect below.\n-Zsanitizer=address -Zbuild-std (nightly): ASan reports stack-buffer-overflow / stack-use-after-scope from the fake-Consumer\u0027s try_pop walking off the Sender frame.\nThis matches the SIGSEGV reported in your own issue #3.\n\nSmoking-gun upstream evidence\nsrc/lib.rs:975 in the project\u0027s test suite carries a TODO:\n\n// TODO: failures\n// - failed with assertion on line 394 in send fn\n//   assert!(second.is_none())\nThat is the assertion site of the transmute block (line 396 in 0.2.0 / master). You have observed try_pop() returning a non-None value where logically there should be none, which is exactly what reading random bytes from the Sender\u0027s send_new / inner fields produces, and the symptom has been marked as a flaky test rather than recognised as UB.\n\nImpact\nReachable from 100% safe Rust. Concrete UB primitives:\n\nOOB read of bytes adjacent to the Sender\u003cT\u003e struct via fake Consumer\u003cT\u003e::try_pop(). The popped T is returned through Err(SendError(t)) to safe-code, an allocator-layout-controlled leak of process memory.\nOOB write via fake Arc::drop AtomicUsize::fetch_sub on bytes that are actually the real Arc::ptr value of the Sender.\nAllocator corruption via fake Arc::drop calling dealloc(Layout::for_value(...)) on a non-allocated address. The Sender struct holds the real Arc\u003cInner\u003e immediately after the producer field; the deallocator call therefore uses a layout the allocator never allocated, which on glibc is a confirmed double-free / arbitrary-bucket-poisoning primitive, and on hardened allocators (jemalloc-secure, mimalloc-secure) is an immediate abort.\nSecondary defect (same call path, bonus)\nSender::send line 369:\n\nself.send_new.send(new_consumer).unwrap();\nWhen the Sender\u0027s message queue is full, a fresh bounded_spsc_queue::Channel is allocated and the new Consumer\u003cT\u003e is shipped over an std::sync::mpsc side-channel to the Receiver. If the Receiver has already been dropped, receive_new is gone and this unwrap() panics. The panic surfaces in your own test suite, issue #2 (tests::port_gone_concurrent panicked at src/lib.rs:369) and the in-source TODO at lines 365-368 already note the question \"Are we sure that this is safe to unwrap or should we handle the result explicitly ?\".\n\nThe fix is to return Err(SendError(t)) instead of unwrapping, same shape as the channel-closed result the function already returns on the connected-false path. This is not a memory-safety defect, only a panic, but it lives on the same TX/RX-race code path and a single coordinated patch can address both. Filing it here so we cover the full call site in one cycle.\n\nSuggested patch (primary defect)\nReplace the pointer-as-value transmute with a value-level read and a ManuallyDrop to suppress the alias\u0027s Producer::drop on subsequent exit:\n\nunsafe {\n    use core::mem::ManuallyDrop;\n\n    // Sound value-level transmute: Producer\u003cT\u003e and Consumer\u003cT\u003e are both\n    // newtypes around Arc\u003cBuffer\u003cT\u003e\u003e, so the value layouts match.\n    // ptr::read takes ownership of the Producer\u0027s bytes without running\n    // Producer\u0027s Drop.\n    let producer_val: spsc::Producer\u003cT\u003e = std::ptr::read(self.producer.get());\n    let consumer    : spsc::Consumer\u003cT\u003e = std::mem::transmute(producer_val);\n\n    let first  = consumer.try_pop();\n    let second = consumer.try_pop();\n    assert!(second.is_none());\n    if let Some(t) = first {\n        return Err(SendError(t));\n    }\n\n    // consumer drops here; the same memory backs `producer`, so suppress\n    // the double Producer drop:\n    let _ = ManuallyDrop::new(consumer);\n}\nCleaner: restructure Sender\u003cT\u003e to hold producer and consumer in a private enum Endpoint\u003cT\u003e so no transmute is required, or use the bounded_spsc_queue::Producer\u003cT\u003e::reclaim() escape hatch if available.\n\nSuggested patch (secondary defect)\nif let Err(std::sync::mpsc::SendError(_)) = self.send_new.send(new_consumer) {\n    // Receiver has been dropped: take the message back as the public\n    // SendError, the same way the connected==false early-return does.\n    return Err(SendError(t));\n}\nRegression test (release-mode, race shape)\n#[test]\nfn race_disconnect_does_not_corrupt_sender_or_abort() {\n    for _ in 0..200 {\n        let (tx, rx) = unbounded_spsc::channel::\u003cBox\u003cu64\u003e\u003e();\n        let h = std::thread::spawn(move || {\n            for _ in 0..10_000 {\n                let _ = tx.send(Box::new(0xDEAD_BEEF));\n            }\n        });\n        drop(rx);\n        h.join().unwrap();\n    }\n}\nReverse dependencies\nTwo crates on crates.io depend on unbounded-spsc, both owned by you: apis (process-calculus framework) and gooey-rs (tile-UI library, unbounded-spsc gated behind opengl/fmod features). The OpenGL/FMOD callback-mailbox use is a natural rx-drop-during-tx-send scenario at scene-graph teardown. A single coordinated bump cycle is feasible.\n\nResearcher\nBerkant Koc me@berkoc.com\nPGP: 0C588DFD76204987284213EA0AC529C41F8AA5D6",

  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix double-free of blocks due to wrong extents moved_len\n\nIn ext4_move_extents(), moved_len is only updated when all moves are\nsuccessfully executed, and only discards orig_inode and donor_inode\npreallocations when moved_len is not zero. When the loop fails to exit\nafter successfully moving some extents, moved_len is not updated and\nremains at 0, so it does not discard the preallocations.\n\nIf the moved extents overlap with the preallocated extents, the\noverlapped extents are freed twice in ext4_mb_release_inode_pa() and\next4_process_freed_data() (as described in commit 94d7c16cbbbd (\"ext4:\nFix double-free of blocks with EXT4_IOC_MOVE_EXT\")), and bb_free is\nincremented twice. Hence when trim is executed, a zero-division bug is\ntriggered in mb_update_avg_fragment_size() because bb_free is not zero\nand bb_fragments is zero.\n\nTherefore, update move_len after each extent move to avoid the issue.",
