      "value": "In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, several locations which shift ids translate user/group ids before performing operations in the lower filesystem were translating them into init_user_ns, whereas they should have been translated into the s_user_ns for the lower filesystem. This resulted in using ids other than the intended ones in the lower fs, which likely did not map into the shifts s_user_ns. A local attacker could use this to possibly bypass discretionary access control permissions."

      "value": "En shiftfs, un parche no upstream para el Kernel de Linux  incluido en las series kernel de Ubuntu versiones 5.0 y 5.3, varias ubicaciones que desplazan los ids traducen los ids de usuario/grupo antes de realizar operaciones en el sistema de archivos inferior los estaban traduciendo a init_user_ns, mientras que deber\u00edan haber sido traducidos a s_user_ns para el sistema de archivos inferior. Esto dio lugar a que se utilizaran ids distintos de los previstos en los fs inferiores, que probablemente no se mapearon en los shifts s_user_ns. Un atacante local podr\u00eda usar esto para posiblemente eludir los permisos de control de acceso discrecional."
