Dirty COW
Dirty COW is a privilege escalation vulnerability in the Linux kernel that exploits the copy-on-write mechanism and can be used to break through container boundaries or obtain system privileges.
Timeline (last 90 days)
Kernel privilege-escalation vulnerabilities (such as Dirty COW and the runc escape vulnerability CVE-2019-5736) may be exploited to break out of the container boundary and thereby access the host machine or other tenants' containers.
Historically, several well-known escape vulnerabilities (such as Dirty COW, Dirty Pipe, and the overlayfs privilege escalation series) all stemmed from kernel subsystem flaws.
