CVE-2026-58926
EVS HAL Use-After-Free Vulnerability
Description
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.
