# Android kernel: fence reuse use-after-free lets local apps gain kernel privileges

Link for people: https://infrastack.ai/live/CVE-2026-59609 (this .md is for agents)

A use-after-free in the kernel's fence manager (fence_manager.c, fence_manager_extract_iif) lets a local process corrupt kernel memory by reusing a fence identifier. An attacker who can run code on the device can escalate to higher privileges, with no user interaction needed.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

In fence_manager_extract_iif of fence_manager.c, there is a possible way to corrupt kernel memory via fence identifier reuse due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
