Lifecycle Timeline
1DescriptionNVD
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.
AnalysisAI
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. Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, no authentication required.
Technical ContextAI
This vulnerability is classified under CWE-362. 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. Affected products include: Systemd Project Systemd, Redhat Enterprise Linux, Redhat Enterprise Linux Aus, Redhat Enterprise Linux Desktop, Redhat Enterprise Linux Server. Version information: prior to 234.
