CVE-2022-0847

CVSS 7.8 HIGHEPSS 89.1%● KEVCWE-665
En resumen

Una falla en el kernel de Linux permite que usuarios sin privilegios escriban en archivos de solo lectura mediante memoria no inicializada en funciones de pipe, posibilitando escalada de privilegios.

Detalle técnico

La vulnerabilidad existe en las funciones copy_page_to_iter_pipe y push_pipe, donde el miembro 'flags' de la estructura de búfer de pipe no se inicializa adecuadamente, permitiendo que valores obsoletos persistan. Un atacante local sin privilegios puede explotarlo para escribir datos arbitrarios en páginas de page cache vinculadas a archivos de solo lectura, eludiendo controles de acceso y escalando privilegios.

Resumen generado y traducido por IA a partir de la descripción oficial.
A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.
