CVE-2026-89934— iio: light: ltrf216a: fix runtime PM reference leak in error path

Quick assessment

Affected
Linux Linux
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，以下漏洞已得到修复： iio: light: ltrf216a: 修复错误路径中运行时电源管理（runtime PM）引用泄漏问题 函数通过调用 获取一个运行时电源管理引用。然而，如果 失败，该函数会立即返回，而未释放该引用。 这导致运行时电源管理的使用计数不平衡，从而阻止设备在读取失败后自动进入挂起状态。 修复方法是在从错误路径返回之前，先释放运行时电源管理引用。

Vulnerability Title
iio: light: ltrf216a: fix runtime PM reference leak in error path
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: iio: light: ltrf216a: fix runtime PM reference leak in error path ltrf216a_get_lux() acquires a runtime PM reference by calling ltrf216a_set_power_state(data, true). However, if ltrf216a_read_data() fails, the function returns immediately without dropping the reference. This leaves the runtime PM usage count unbalanced, preventing the device from autosuspending after a failed read. Fix this by releasing the runtime PM reference before returning from the error path.
