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，已解决以下漏洞： bnxt_en：修复对硬件监控事件处理函数的调用 函数的第一个参数本应是硬件监控设备（hardware monitoring device）。然而，bnxt 驱动程序错误地传入了平台设备（platform device）作为第一个参数。这种 API 使用不当会导致未定义行为，并可能引发系统崩溃。 修复方式： 改为传入正确的硬件监控设备作为参数，从而解决问题。

Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix call to hardware monitoring event handler The first parameter of hwmon_notify_event() is supposed to be the hardware monitoring device.
