CVE 描述

platform/x86: int3472: Fix double free of GPIO device during unregister

In the Linux kernel, the following vulnerability has been resolved: platform/x86: int3472: Fix double free of GPIO device during unregister regulator_unregister() already frees the associated GPIO device. On ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to random failures when other drivers (typically Intel THC) attempt to allocate interrupts. The root cause is that the reference count of the pinctrl_intel_platform module unexpectedly drops to zero when this driver defers its probe. This behavior can also be reproduced by unloading the module directly. Fix the issue by removing the redundant release of the GPIO device during regulator unregistration.

CVE 信息

EPSS

EPSS 是一种预测漏洞被利用可能性的评分模型。

EPSS 评分

EPSS 模型生成一个介于 0 到 1(即 0% 到 100%)之间的概率评分。评分越高,漏洞被利用的可能性越大。

EPSS 百分位

百分位用于根据 EPSS 评分对 CVE 进行排名。例如,EPSS 百分位为第 95 的 CVE,其被利用的可能性高于 95% 的其他 CVE。因此,百分位可用于比较不同 CVE 的 EPSS 评分。
