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).
Between late September and early October 2026, seven South Korean financial institutions were breached, impacting around 66,000 individuals and 2,200 corporations. The attacks were linked to ARTEX, an AI-driven autonomous penetration testing framework. Investigations uncovered exposed infrastructure hosting AI model-routing components, exploitation tools, and proxy management utilities. The operation leveraged multiple AI models and included various attack artifacts such as reconnaissance tools, exploitation chains, privilege escalation exploits, and scripts targeting cryptocurrency exchanges and mobile devices. The infrastructure spanned multiple countries with over 1,300 IP addresses identified.
