Local kernel compromise via Binder offsets overwrite
Published Sep 18, 2024 · Updated Aug 5, 2026
Use-after-free in the Binder driver in Linux allows local users to compromise the kernel through crafted local transactions. In drivers/android/binder.c, the transaction path copies unchecked raw data past the data section into the offsets array, then unwinds objects using corrupted offsets and prematurely releases Binder nodes. Access to a Binder device is required; an unprivileged local user can mount binderfs in a user namespace and obtain kernel-memory disclosure or writes, or cause a kernel panic.
