Title

Android on Nexus信息泄露漏洞

Description

Android on Nexus 6和7是美国谷歌（Google）公司和开放手持设备联盟（简称OHA）共同开发的一套运行于Nexus 6和7（智能手机）中并以Linux为基础的开源操作系统。Linux kernel是美国Linux基金会发布的操作系统Linux所使用的内核。 Nexus 6和7 (2013)设备中的Android 2016-08-05之前版本中使用的Linux kernel 4.7及之前的版本中的kernel/resource.c文件中的‘ioresources_initas’函数存在安全漏洞，该漏洞源于程序对‘/proc/iomem’文件使用弱的权限。攻击者通过阅读此文件利用该漏洞获取敏感信息。

CVE-2015-8944 (GCVE-0-2015-8944)

Vulnerability from cvelistv5 – Published: 2016-08-06 10:00 – Updated: 2024-08-06 08:36

Summary

The ioresources_init function in kernel/resource.c in the Linux kernel through 4.7, as used in Android before 2016-08-05 on Nexus 6 and 7 (2013) devices, uses weak permissions for /proc/iomem, which allows local users to obtain sensitive information by reading this file, aka Android internal bug 28814213 and Qualcomm internal bug CR786116. NOTE: the permissions may be intentional in most non-Android contexts.
