Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux 内核中已修复以下漏洞： HID: sensor-hub: 修复 sensor_hub_get_feature 中的越界写入问题 函数虽然将返回值限制在调用者缓冲区大小内，但其内部的复制循环仍会按照 字节的大小来复制每个报告值。一个恶意的 HID 描述符可以声明一个很大的特性字段大小，而 IIO 调用者可能仅提供一个较小的栈缓冲区（例如一个 大小的缓冲区），从而引发越界写入。 HID 核心模块将解析后的报告值存储在 槽位中，并将提取的值截断为 32 位。修复措施包括：拒绝需要超过一个槽位/值的特性字段，对

Vulnerability Title
HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature sensor_hub_get_feature() clamps its return value to the caller's buffer size, but the copy loop still copies field->report_size / 8 bytes for each report value. A malicious HID descriptor can advertise a large feature field size while an IIO caller supplies a small stack buffer, such as a single s32, causing an out-of-bounds write. HID core stores parsed report values in __s32 slots and clamps extracted values to 32 bits. Reject feature fields that require more than one slot per value, guard the total byte count calculation, and clamp each per-value copy to the remaining caller buffer.
