FKIE_CVE-2025-5054

Vulnerability from fkie_nvd - Published: 2025-05-30 18:15 - Updated: 2026-06-17 09:47
Severity
4.7 (Medium) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
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. When 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).
