CVE-2022-50281

Service interruption via unreleased platform devices

Published Sep 15, 2025 · Updated Sep 15, 2025

Resource leak in the MIPS SGI-IP27 bridge code in Linux allows local users to interrupt service through repeated device-registration failures. On bridge setup error paths, bridge_platform_create() returns after a platform-device operation fails without releasing the device; a later xtalk-bridge failure also leaves sgi_w1 resources registered. Reachability requires an SGI-IP27 system and local low-privileged access capable of repeatedly reaching those failure paths; the documented consequence is availability loss without confidentiality or integrity impact.
