Descriptions
lock order inversion in transitive grant copy handling As part of XSA-226 a missing cleanup call was inserted on an error handling path. While doing so, locking requirements were not paid attention to. As a result two cooperating guests granting each other transitive grants can cause locks to be acquired nested within one another, but in respectively opposite order. With suitable timing between the involved grant copy operations this may result in the locking up of a CPU.
Inversión del orden de bloqueo en el manejo de la copia de concesión transitiva Como parte de XSA-226 fue insertada una llamada de limpieza que faltaba en una ruta de manejo de errores. Mientras era hecho esto, no fue prestado atención a los requisitos de bloqueo. Como resultado, dos invitados cooperantes que son concedidos mutuamente subvenciones transitivas pueden causar que se adquieran bloqueos anidados uno dentro del otro, pero en el orden opuesto respectivamente. Con una sincronización apropiada entre las operaciones de copia de concesión implicadas, esto puede provocar el bloqueo de una CPU
Multiple vulnerabilities have been found in Xen, the worst of which can lead to arbitrary code execution. Versions greater than or equal to 4.16.6_pre1 are affected.
