CVE-2019-13226

• Severity: high (CVSS 7.0 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2019-07-04 · updated 2026-06-17
• Weakness: CWE-59

Description

deepin-clone before 1.1.3 uses a predictable path /tmp/.deepin-clone/mount/<block-dev-basename> in the Helper::temporaryMountDevice() function to temporarily mount a file system as root. An unprivileged user can prepare a symlink at this location to have the file system mounted in an arbitrary location. By winning a race condition, the attacker can also enter the mount point, thereby preventing a subsequent unmount of the file system.

Affected products

• Deepin-Clone: before 1.1.3 — fixed in 1.1.3
• Fedoraproject Fedora: 30

How to fix

Upgrade to a fixed version: Deepin-Clone 1.1.3. Check the vendor advisory for mitigations.
