Object-unwinding errors via misaligned Binder offsets
Published Apr 24, 2024 · Updated Aug 5, 2026
Improper offset validation in the Linux kernel Binder driver allows local users to pass misaligned transaction data into object unwinding. The binder_get_object() function copies an object from user memory without first requiring its transaction-buffer offset to be four-byte aligned. A local process that can submit Binder transactions can supply a misaligned offset; the public record specifies no resulting crash, disclosure, or privilege gain.
