Title: Linux kernel资源管理错误漏洞（CNVD-2019-41704）

Description:

Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。

Linux kernel 5.3.11及之前版本中的drivers/char/ipmi/ipmi_msghandler.c文件的‘the __ipmi_bmc_register()’函数存在资源管理错误漏洞。该漏洞源于网络系统或产品对系统资源（如内存、磁盘空间、文件等）的管理不当。攻击者可利用该漏洞通过触发ida_simple_get（）故障（aka CID-4aa7afb0ee20）来导致拒绝服务（内存消耗）。

Severity: 高

Severity ?

CWE

Summary

A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of this because an attacker cannot realistically control this failure at probe time
