      "title": "rust_binder: use a u64 stride when cleaning up the offsets array",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nrust_binder: use a u64 stride when cleaning up the offsets array\n\nAllocation's Drop walks the offsets array (binder_size_t = u64 entries),\ncleaning up the objects, but it used usize instead of u64 for both the\nstride and the per-entry read.\n\nOn 64-bit kernels (usize == u64) this is harmless, but on 32-bit kernels\nit walks the 8-byte entries in 4-byte steps, iterating an N-entry array\n2N times, and reads the always-zero high word as offset 0, cleaning up\nthe object at offset 0 N extra times. As a result the referenced node or\nhandle ends up with a lower reference count than it actually has (a\nrefcount over-decrement), and binder's reference accounting is corrupted;\nfor example, the owner can be notified of a strong reference release\n(BR_RELEASE) even though references still remain.\n\nChange the stride to u64, and read each entry as a u64, narrowing it to\nusize with try_into().\n\nOn 32-bit ARM, when this over-decrement would drive a count below zero,\nthe driver's existing refcount guard refuses it and fires:\n\n  rust_binder: Failure: refcount underflow!",
