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 sensitive information by reading the pagemap file. The exploitation allows local users to obtain sensitive physical-address information.Recommendations
For Linux kernel versions prior to 3.19.3, update to version 3.19.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the pagemap file to minimize the risk of exploitation.
