[PATCH openEuler-1.0-LTS] misc/libmasm/module: Fix two use after free in ibmasm_init_one
by Zhang Changzhong 12 Jun '24

From: Lv Yunlong <lyl2019(a)mail.ustc.edu.cn> stable inclusion from stable-v4.19.198 commit 481a76d4749ee3a27f902ba213fdcbb4bb39720e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RLTD CVE: CVE-2021-47334 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7272b591c4cb9327c43443f67b8fbae7657dd9ae ] In ibmasm_init_one, it calls ibmasm_init_remote_input_dev(). Inside ibmasm_init_remote_input_dev, mouse_dev and keybd_dev are allocated by input_allocate_device(), and assigned to sp->remote.mouse_dev and sp->remote.keybd_dev respectively. In the err_free_devices error branch of ibmasm_init_one, mouse_dev and keybd_dev are freed by input_free_device(), and return error. Then the execution runs into error_send_message error branch of ibmasm_init_one, where ibmasm_free_remote_input_dev(sp) is called to unregister the freed sp->remote.mouse_dev and sp->remote.keybd_dev. My patch add a "error_init_remote" label to handle the error of ibmasm_init_remote_input_dev(), to avoid the uaf bugs.

This means that sometimes we can increase the refcount in `prepare_fb` and don't decrease it in `cleanup_fb`. The opposite can also be true. In fact, the struct drm_plane .state shouldn't be accessed directly but instead, the `drm_atomic_get_new_plane_state()` helper function should be used. So, we could stick to this check, but using `drm_atomic_get_new_plane_state()`. But actually, this check is not really needed. We can increase and decrease the refcount symmetrically without problems. This is going to make the code more simple and consistent.
