CVE-2024-26993

一、漏洞信息
漏洞编号：CVE-2024-26993
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
CVSS V2.0分值：
BaseScore：0.0 Low
Vector：CVSS：2.0/
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:fs: sysfs: Fix reference leak in sysfs_break_active_protection()The sysfs_break_active_protection() routine has an obvious referenceleak in its error path. If the call to kernfs_find_and_get() fails thenkn will be NULL, so the companion sysfs_unbreak_active_protection()routine won t get called (and would only cause an access violation bytrying to dereference kn->parent if it was called). As a result, thereference to kobj acquired at the start of the function will never bereleased.Fix the leak by adding an explicit kobject_put() call when kn is NULL.
