Title

Linux kernel资源管理错误漏洞（CNVD-2019-32355）

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（longterms）4.9.190之前的4.9.x版本和4.14.139之前的4.14.x版本中存在资源管理错误漏洞，该漏洞源于程序未能将对net/ipv4/tcp_output.c文件的修改正确地应用到之前的longterm kernels上。攻击者可利用该漏洞造成内核崩溃或可能提升权限。

CVE-2019-15239 (GCVE-0-2019-15239)

Vulnerability from cvelistv5 – Published: 2019-08-20 07:25 – Updated: 2024-08-05 00:42

Summary

In the Linux kernel, a certain net/ipv4/tcp_output.c change, which was properly incorporated into 4.16.12, was incorrectly backported to the earlier longterm kernels, introducing a new vulnerability that was potentially more severe than the issue that was intended to be fixed by backporting. Specifically, by adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation. NOTE: this affects (for example) Linux distributions that use 4.9.x longterm kernels before 4.9.190 or 4.14.x longterm kernels before 4.14.139.

              "value": "In the Linux kernel, a certain net/ipv4/tcp_output.c change, which was properly incorporated into 4.16.12, was incorrectly backported to the earlier longterm kernels, introducing a new vulnerability that was potentially more severe than the issue that was intended to be fixed by backporting. Specifically, by adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation. NOTE: this affects (for example) Linux distributions that use 4.9.x longterm kernels before 4.9.190 or 4.14.x longterm kernels before 4.14.139."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
