"value": "A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out."
},

"lang": "es",
"value": "Se ha encontrado un error en el subsistema de archivos NFS41+ del kernel de Linux. Las comparticiones de NFS41+ montadas en diferentes espacios de nombre al mismo tiempo pueden hacer que bc_svc_process() emplee el ID de canal trasero err\u00f3neo y provoque una vulnerabilidad de uso de memoria previamente liberada. As\u00ed, un usuario contenedor malicioso puede provocar la corrupci\u00f3n de la memoria host del kernel y un p\u00e1nico del sistema. Debido a la naturaleza del error, no se puede descartar totalmente un escalado de privilegios."
