Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： 总线：MHI 主机：修复 EDL sysfs 创建失败时的控制器清理问题 在创建可选的 sysfs 文件之前，会先添加控制器设备。如果 失败，原有的错误处理路径仅释放了设备引用，却未注销设备，导致设备仍处于注册状态。 因此，在错误处理路径中，应在调用 之前调用 ，以确保设备被正确注销和清理。

Vulnerability Title
bus: mhi: host: Fix controller cleanup on EDL sysfs failure
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: host: Fix controller cleanup on EDL sysfs failure
mhi_register_controller() adds the controller device before creating the
optional trigger_edl sysfs file. If sysfs_create_file() fails, the error
path only drops the device reference and leaves the device registered.
Hence, call device_del() in the error path before put_device().
