CVE-2026-64469

Local privilege escalation via Binder teardown race

Published Jul 25, 2026 · Updated Jul 25, 2026

Use-after-free in the Linux kernel Binder subsystem allows local users to corrupt kernel memory through Binder device ioctls. binder_thread_release() accesses a binder_transaction after t->to_proc is cleared while binder_free_transaction() can free it because t->to_proc is not read under the transaction lock. Low-privileged access to Binder or a private BinderFS device is sufficient, enabling kernel-memory disclosure, arbitrary writes, code execution, or a kernel panic.
