CVE-2026-54229

Full vulnerability record from the local CVENow database.

Description

A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DD_OPEN_READONLY and calls dd_chown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows an attacker to gain filesystem-level control of the dump directory while privileged event scripts are still running.

ChownProblemDir abre el directorio de volcado con DD_OPEN_READONLY y llama a dd_chown para cambiar la propiedad de todos los archivos al uid del llamador, teniendo éxito incluso mientras los manejadores de eventos post-creación mantienen un bloqueo de escritura. Esto permite a un atacante obtener control a nivel de sistema de archivos del directorio de volcado mientras los scripts de eventos privilegiados aún se están ejecutando."
