CVE-2024-26606

Local Binder thread hang via missed self-wakeup

Published Feb 26, 2024 · Updated May 11, 2026

Denial of service in the Linux Binder driver allows local users to hang Binder threads by queuing work for their own thread. In drivers/android/binder.c, binder_poll() fails to wake an epoll thread when its BINDER_WRITE_READ request queues self-work without a read buffer. Local Binder-device access and a polling workflow are required; the thread can wait indefinitely with queued work unhandled, and later commands do not wake it.
