About this tag
The local dos tag on WindowsForum.com covers denial-of-service vulnerabilities that require local access to exploit. Content includes Linux kernel flaws such as CVE-2024-26785 in iommufd and CVE-2024-26758 in the md RAID subsystem, as well as Windows-specific issues like CVE-2026-21525 in RasMan and CVE-2025-29477 in Fluent Bit. These threads discuss race conditions, resource exhaustion, and improper link resolution that can crash or hang systems. The tag is relevant for IT administrators and security professionals tracking locally exploitable DoS vectors across both Windows and Linux environments.
