Udisks2: Out-of-bounds Read in storaged-project udisks (CVE-2025-8067)
A flaw was found in the Udisks daemon, where it allows unprivileged users to create loop devices using the D-BUS system. This is achieved via the loop device handler, which handles requests sent through the D-BUS interface. As two of the parameters of this handle, it receives the file descriptor list and index specifying the file where the loop device should be backed. The function itself validates the index value to ensure it isn't bigger than the maximum value allowed. However, it fails to validate the lower bound, allowing the index parameter to be a negative value. Under these circumstances, an attacker can cause the UDisks daemon to crash or perform a local privilege escalation by gaining access to files owned by privileged users.

Technical Summary
CVE-2025-8067 is an out-of-bounds read vulnerability in the UDisks Daemon component of the Udisks2 project, which provides tools and libraries to access and manipulate disks and storage devices. This vulnerability affects Red Hat Enterprise Linux 7 Extended Lifecycle Support versions. Red Hat has issued a security advisory (RHSA-2025:16130) and released updated packages (udisks2-2.8.4-1.el7_9.2) to fix the issue. The advisory rates the security impact as Important (high severity). No CVSS score is provided in the advisory. The vulnerability is tracked under CWE-125 (Out-of-bounds Read).
Potential Impact
The vulnerability allows an out-of-bounds read in the UDisks Daemon, which may lead to information disclosure or other unintended behavior depending on how the daemon processes data. The exact impact details and exploitation scenarios are not provided in the advisory. There are no known exploits in the wild currently reported.
Mitigation Recommendations
Red Hat has released updated udisks2 packages that address this vulnerability. Users of Red Hat Enterprise Linux 7 Extended Lifecycle Support should apply the security update (udisks2-2.8.4-1.el7_9.2) as soon as possible. Detailed update instructions are available in the Red Hat advisory and knowledge base article (https://access.redhat.com/articles/11258). No additional mitigation steps are indicated by the vendor.
