Vulnerability from cnvd

Title: Linux kernel拒绝服务漏洞（CNVD-2018-07889）

Description:

Linux kernel是一种计算机操作系统内核，以C语言和汇编语言写成，符合POSIX标准，按GNU通用公共许可证发行。

Linux kernel 4.13.5之前版本中的arch/powerpc/kernel/ptrace.c中的flush_tmregs_to_thread函数存在拒绝服务漏洞。该漏洞产生的原因是缺少处理器特性检查和核心转储路径中错误使用事务内存（TM）指令。攻击者可利用POWER主机上的核心转储期间的非特权用户空间利用该漏洞导致客户机内核崩溃。

Severity: 高

CWE-391

Summary

In the flush_tmregs_to_thread function in arch/powerpc/kernel/ptrace.c in the Linux kernel before 4.13.5, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erroneous use of transactional memory (TM) instructions in the core dump path, leading to a denial of service.
