CVE-2019-14898: 
Linux Kernel vulnerability analysis and mitigation

CVE-2019-14898 is a vulnerability affecting the Linux kernel before version 5.0.10. The issue stems from an incomplete fix for a previous vulnerability (CVE-2019-11599). The vulnerability was discovered in 2019 and involves a race condition with mmget_not_zero or get_task_mm calls (NVD, CVE).

The vulnerability is characterized by a race condition between mmget_not_zero()/get_task_mm() and core dumping operations. It has been assigned a CVSS v3.1 Base Score of 7.0 (HIGH) with the vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H. The vulnerability is classified under CWE-667 (Improper Locking) and CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization) (NVD).

A local user could exploit this vulnerability to obtain sensitive information, cause a denial of service, or potentially have other unspecified impacts by triggering the race condition (NVD).

The vulnerability requires local access and high complexity to exploit. It requires low privileges and no user interaction. The attack complexity is rated as high, indicating that specific conditions need to be met for successful exploitation (NVD).

The vulnerability was fixed in Linux kernel version 5.0.10 and backported to various stable kernel versions. Organizations should update their Linux kernel to a patched version. Red Hat has released security updates to address this vulnerability in their products through various security advisories (Red Hat Advisory).
