Gain Access
DESCRIPTION
Linux Kernel could allow a remote attacker to execute arbitrary code on the system, caused by an issue with munmap() racing with pagemap_read() which leads to a page use-after-free flaw. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
