CVE-2026-5674: Uncontrolled Search Path Element in Red Hat Red Hat Enterprise Linux 10
A flaw was found in PipeWire, a multimedia server. This vulnerability allows an attacker to escape sandboxed applications, such as Flatpak, by exploiting PipeWire's PulseAudio compatibility layer. An attacker with minimal permissions within a sandboxed environment can load a malicious library, leading to arbitrary code execution outside the sandbox and potential compromise of the user's system.
AI Analysis
Technical Summary
CVE-2026-5674 is a sandbox escape vulnerability in PipeWire's PulseAudio compatibility layer. An attacker with limited permissions inside a sandbox can load a malicious library, resulting in arbitrary code execution outside the sandbox. This vulnerability is classified under CWE-427 (Uncontrolled Search Path Element). Red Hat has issued a security advisory and released updated PipeWire packages for Red Hat Enterprise Linux 10 to fix this issue.
Potential Impact
Successful exploitation allows an attacker to break out of sandboxed environments, such as Flatpak, and execute arbitrary code with the privileges of the user outside the sandbox. This can lead to full compromise of the user's system, including confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Red Hat has released updated PipeWire packages that address this vulnerability. Users of Red Hat Enterprise Linux 10 and its variants should apply the security update as described in Red Hat advisory RHSA-2026:47083 and the article at https://access.redhat.com/articles/11258.
