# Android EVS HAL: race lets a privileged client free a buffer in use

The EVS (Extended View System) hardware abstraction layer has a use-after-free race: a privileged client can free a buffer handle while the producer thread still uses it, via doneWithFrame and setMaxFramesInFlight. An attacker could manipulate freed heap memory and leak file descriptors from the EVS HAL process.

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

## From the sources

A Use-After-Free (UAF) vulnerability exists in the EVS HAL, allowing a privileged client to free a `buffer_handle_t` while the producer thread is still using it. This race condition, triggered via `doneWithFrame` and `setMaxFramesInFlight`, enables an attacker to manipulate freed heap memory, potentially leading to the leakage of file descriptors from the EVS HAL process.
