CVE-2025-27148

Local privilege escalation via temporary-library replacement race

Published Feb 25, 2025 · Updated Feb 25, 2025

Local privilege escalation in Gradle Build Tool 8.12 allows local users to execute code with a build user's privileges via a file race. A default native-platform initialization path copies native binaries into the shared system temporary directory, where another user can rapidly delete and replace them before loading. Exposure requires a Unix-like host whose temporary directory lacks sticky-bit protection and is executable; Windows and modern macOS are unaffected.
