oom denial of service

About this tag
The oom denial of service tag covers vulnerabilities and exploits that cause out-of-memory conditions, leading to system or service crashes. Recent discussions include CVE-2026-43398, a Linux kernel bug in the AMDGPU driver where oversized user values in the user queue wait ioctl can trigger OOM, and CVE-2025-68384, an Elasticsearch vulnerability allowing authenticated low-privileged users to cause uncontrolled resource allocation and OOM-based denial of service. These threads highlight the importance of patching and resource limits in graphics drivers and enterprise search platforms.
