Linux Kernel 'fs/proc/base.c' Local Information Disclosure Vulnerability

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the 'procpidstack' function in the fs/proc/base.c file in Linux kernel versions 4.18.11 and earlier. A local attacker can exploit th...

CVE-2018-17972

An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents...

CVE-2018-17972: Concurrent Execution using Shared Resource with Improper Synchronization

An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents...

CVE-2016-7916

Race condition in the environread function in fs/proc/base.c in the Linux kernel before 4.5.4 allows local users to obtain sensitive information from kernel memory by reading a /proc//environ file during a process-setup time interval in which environment-variable copying is incomplete...

CVE-2016-0823

The pagemapopen function in fs/proc/taskmmu.c in the Linux kernel before 3.19.3, as used in Android 6.0.1 before 2016-03-01, allows local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721...

CVE-2016-0823: Exposure of Sensitive Information to an Unauthorized Actor

The pagemapopen function in fs/proc/taskmmu.c in the Linux kernel before 3.19.3, as used in Android 6.0.1 before 2016-03-01, allows local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721...

PT-2016-1585

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.19.3 Description The issue is related to the pagemap open function in fs/proc/task mmu.c of the Linux kernel, which lacks protection of internal data. This can be exploited by a local attacker to gain access to...

CVE-2014-3940

The Linux kernel through 3.14.5 does not properly consider the presence of hugetlb entries, which allows local users to cause a denial of service memory corruption or system crash by accessing certain memory locations, as demonstrated by triggering a race condition via numamaps read operations...

PT-2014-5620

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.14.5 Description The issue allows local users to cause a denial of service, resulting in memory corruption or system crash, by accessing certain memory locations. This can be achieved by triggering a race...
