CVE-2022-22068Public exploit

Kernel-data disclosure via queued freed-buffer pointer

Published Jun 14, 2022 · Updated Aug 3, 2024

Use-after-free in Qualcomm Snapdragon NPU drivers allows local users to read kernel data through asynchronous execution events. app_msg_proc queues an event containing a stats_buf pointer, npu_unload_network_v2 frees that buffer, and npu_process_kevent later copies the freed contents to user space. An untrusted app with access to the NPU device ioctls can trigger the asynchronous execute, unload, and receive-event sequence without user interaction.
