Android - Use-After-Free in binder_thread_read

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 2 public exploits for CVE-2019-2025. PoCs published by Google Security Research, codecat007.

AI-analyzed exploit summary This exploit demonstrates a race condition in the Linux kernel's binder driver (CVE-2019-2025), allowing userspace to free buffers in a kernel-managed shared memory region. The PoC triggers a use-after-free condition by exploiting a small race window in the BC_FREE_BUFFER command.

Description

In binder_thread_read of binder.c, there is a possible use-after-free due to improper locking. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-116855682References: Upstream kernel

This PoC exploits a use-after-free vulnerability in the Android SensorService (CVE-2019-2025) by repeatedly calling `freeBuffer` on the same buffer, leading to memory corruption. The exploit uses multithreading to trigger the race condition and achieve local privilege escalation.
