In the Linux kernel, the following vulnerability has been resolved: rust_binder: use a u64 stride when cleaning up the offsets array Allocation's Drop walks the offsets array (binder_size_t = u64 entries), cleaning up the objects, but it used usize instead of u64 for both the stride and the per-entry read. On 64-bit kernels (usize == u64) this is harmless, but on 32-bit kernels it walks the 8-b…
