CVE-2018-1049
Last modified
CVE-2018-1049 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. In systemd prior to 234 a race condition exists between .mount and .automount units such that automount requests from kernel may not be serviced by systemd resulting in kernel holding the mountpoint and any processes that try to use said mount will hang. A race condition like this may lead to denial of service, until mount points are unmounted.. EPSS estimates a 7.26% chance of exploitation in the next 30 days.
