binder: fix is_failure flag for superseded transaction cleanup
In the Linux kernel, the following vulnerability has been resolved: binder: fix is_failure flag for superseded transaction cleanup When a TF_UPDATE_TXN transaction supersedes a pending async transaction, binder_release_entire_buffer() is called with is_failure=false. Since the superseded transaction was never delivered, binder_apply_fd_fixups() was never called and no fds were installed in the target process. With is_failure=false, the BINDER_TYPE_FDA cleanup handler interprets stale buffer contents as installed fd numbers and passes them to binder_deferred_fd_close(), closing unrelated file descriptors. Pass is_failure=true since the transaction was never delivered to the target, matching the semantics of all other undelivered-transaction cleanup paths.
