CVE-2023-52439

一、漏洞信息
漏洞编号：CVE-2023-52439
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0
CVSS V3.0分值：
BaseScore：7.8 High
Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:uio: Fix use-after-free in uio_opencore-1 core-2-------------------------------------------------------uio_unregister_device uio_open idev = idr_find()device_unregister(&idev->dev)put_device(&idev->dev)uio_device_release get_device(&idev->dev)kfree(idev)uio_free_minor(minor) uio_release put_device(&idev->dev) kfree(idev)-------------------------------------------------------In the core-1 uio_unregister_device(), the device_unregister will kfreeidev when the idev->dev kobject ref is 1. But after core-1device_unregister, put_device and before doing kfree, the core-2 mayget_device. Then:1. After core-1 kfree idev, the core-2 will do use-after-free for idev.2. When core-2 do uio_release and put_device, the idev will be double freed.To address this issue, we can get idev atomic & inc idev reference withminor_lock.
