CVE-2024-42090

一、漏洞信息
漏洞编号：CVE-2024-42090
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0,6.6.0
CVSS V3.0分值：
BaseScore：5.5 Medium
Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFERIn create_pinctrl(), pinctrl_maps_mutex is acquired before callingadd_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl()calls pinctrl_free(). However, pinctrl_free() attempts to acquirepinctrl_maps_mutex, which is already held by create_pinctrl(), leading toa potential deadlock.This patch resolves the issue by releasing pinctrl_maps_mutex beforecalling pinctrl_free(), preventing the deadlock.This bug was discovered and resolved using Coverity Static AnalysisSecurity Testing (SAST) by Synopsys, Inc.

CVE-2024-42090

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER

In create_pinctrl(), pinctrl_maps_mutex is acquired before calling
add_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl()
calls pinctrl_free(). However, pinctrl_free() attempts to acquire
pinctrl_maps_mutex, which is already held by create_pinctrl(), leading to
a potential deadlock.

This patch resolves the issue by releasing pinctrl_maps_mutex before
calling pinctrl_free(), preventing the deadlock.

This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

The Linux kernel CVE team has assigned CVE-2024-42090 to this issue.
