qrtr nameservice

About this tag
The qrtr nameservice tag covers Linux kernel vulnerabilities in the Qualcomm IPC Router (QRTR) name service subsystem. Recent threads detail CVE-2026-46026 (unbounded lookup leading to local DoS), CVE-2026-46038 (memory leak on BYE packet cleanup), and CVE-2026-46047 (use-after-free during nameservice removal). These flaws are narrow, subsystem-specific bugs that can cause denial-of-service or memory corruption. For WindowsForum readers, the relevance lies in mixed-platform environments where Linux runs on Qualcomm hardware, Windows Subsystem for Linux (WSL), or embedded devices. The tag focuses on kernel security, resource accounting, and lifecycle management in networking-adjacent code.
