CVE-2026-96282: Improper Link Resolution Before File Access ('Link Following') in Red Hat Red Hat Enterprise Linux 10
A malicious Flatpak extension can probe the host filesystem to determine what files and directories exist at arbitrary paths, and host directory listings can be disclosed to sandboxed applications using the extension. Additionally, unvalidated extension metadata can cause extension content to be mounted at unintended locations inside the sandbox.
AI Analysis
Technical Summary
This vulnerability arises from improper link resolution ('link following') in Flatpak extensions on Red Hat Enterprise Linux 10. It allows a malicious Flatpak extension to probe the host filesystem, revealing the existence of files and directories at arbitrary paths. Furthermore, unvalidated metadata in the extension can lead to extension content being mounted at unintended locations within the sandbox environment, potentially exposing host directory listings to sandboxed applications.
Potential Impact
The vulnerability does not allow direct compromise of confidentiality, integrity, or availability of the host system but can disclose host directory listings and file existence information to sandboxed applications. The CVSS score of 3.1 reflects a low impact with no confidentiality loss, limited integrity impact, and no availability impact. There are no known exploits in the wild.
Mitigation Recommendations
No explicit patch or remediation status is provided in the available data. Patch status is not yet confirmed—check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-96282 for current remediation guidance. Until a fix is available, restrict installation of untrusted Flatpak extensions and monitor vendor updates.
