Descriptions

In FreeBSD 12.1-STABLE before r356908, 12.1-RELEASE before p5, 11.3-STABLE before r356908, and 11.3-RELEASE before p9, a race condition in the cryptodev module permitted a data structure in the kernel to be used after it was freed, allowing an unprivileged process can overwrite arbitrary kernel memory.

En FreeBSD versiones 12.1-STABLE anteriores a r352509, versiones 11.3-STABLE anteriores a r352509 y versiones 11.3-RELEASE anteriores a p9, una condición de carrera en el módulo cryptodev permitía utilizar una estructura de datos en el kernel después de liberarla, permitiendo a un proceso no privilegiado poder sobrescribir la memoria del kernel arbitrariamente.
