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： misc: ad525x_dpot：在 sysfs 文件中驱动核心使用 groups 原本会手动创建每个 RDAC 的 sysfs 文件，并可选择性地创建命令 sysfs 组。这导致 probe（探测）函数需要负责回滚部分已创建的 sysfs 状态，而 remove（移除）函数则需要负责清理 probe 创建的所有文件。 该变更将设备属性移入 I2C 和 SPI 驱动的驱动核心 ，并使用 回调来仅暴露被探测到的设备所支持的属性。采用这种结构后，驱动核心会在 probe 成功

Vulnerability Title
misc: ad525x_dpot: use driver core groups for sysfs files
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: misc: ad525x_dpot: use driver core groups for sysfs files ad_dpot_probe() creates per-RDAC sysfs files manually and then optionally creates the command sysfs group. This leaves probe responsible for rolling back partial sysfs state and makes remove responsible for matching every file that probe created. Move the device attributes into driver core dev_groups for the I2C and SPI drivers and use an is_visible() callback to expose only the attributes supported by the probed device. With this shape, the driver core creates the sysfs files only after probe succeeds and removes them before the remove callback frees the driver data.
