CVE-2026-41163

A flaw was found in bubblewrap when operating in setuid mode. A local user may use ptrace to interfere with the sandbox setup process and gain access to privileged operations that are normally restricted. This could allow an attacker to bypass intended sandboxing restrictions and potentially elevate privileges on the system.

The overlayfs mount support was added in bubblewrap version 0.11.0 and that versions prior to 0.11.0 do not support overlay mounts.\n\nRed Hat products currently ship bubblewrap versions that predate the introduction of overlay mount support. As a result, the vulnerable functionality is not present and Red Hat products are not affected by this issue.\n\n```\n\nAdditionally, RHEL 8 and later install bubblewrap in non-setuid root mode by default.
