{"id":"CVE-2025-5054","details":"Race condition in Canonical apport up to and including 2.32.0 allows a local attacker to leak sensitive information via PID-reuse by leveraging namespaces.\n\n\n\n\nWhen handling a crash, the function `_check_global_pid_and_forward`, which detects if the crashing process resided in a container, was being called before `consistency_checks`, which attempts to detect if the crashing process had been replaced. Because of this, if a process crashed and was quickly replaced with a containerized one, apport could be made to forward the core dump to the container, potentially leaking sensitive information. `consistency_checks` is now being called before `_check_global_pid_and_forward`. Additionally, given that the PID-reuse race condition cannot be reliably detected from userspace alone, crashes are only forwarded to containers if the kernel provided a pidfd, or if the crashing process was unprivileged (i.e., if dump mode == 1).","modified":"2026-04-10T05:29:14.413294Z","published":"2025-05-30T18:15:32.670Z","references":[{"type":"WEB","url":"http://seclists.org/fulldisclosure/2025/Jun/9"},{"type":"ADVISORY","url":"https://ubuntu.com/security/CVE-2025-5054"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7545-1"},{"type":"EVIDENCE","url":"https://www.qualys.com/2025/05/29/apport-coredump/apport-coredump.txt"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-5054.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"2.32.0"}]},{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"20.04"}]},{"events":[{"introduced":"0"},{"last_affected":"22.04"}]},{"events":[{"introduced":"0"},{"last_affected":"24.04"}]},{"events":[{"introduced":"0"},{"last_affected":"24.10"}]},{"events":[{"introduced":"0"},{"last_affected":"25.04"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
