CVE-2019-14898: Race Condition
First published: Wed Nov 20 2019(Updated: )
Linux Kernel is vulnerable to a denial of service, caused by a race condition in between mmget_not_zero()/get_task_mm() and core dumping. By using a specially-crafted system call, a local authenticated attacker could exploit this vulnerability to cause the system to crash or obtain sensitive information.
