P2M pool freeing may take excessively long The P2M pool backing second level address translation for guests may be of significant size. Therefore its freeing may take more time than is reasonable without intermediate preemption checks. Such checking for the need to preempt was so far missing. La liberación del pool P2M puede tardar demasiado El pool P2M que respalda la traducción de direcciones de segundo nivel para huéspedes puede tener un tamaño considerable. Por lo tanto, su liberación puede tomar más tiempo de lo que es razonable sin comprobaciones intermedias de preferencia. • http://www.openwall.com/lists/oss-security/2022/10/11/3 http://xenbits.xen.org/xsa/advisory-410.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TJOMUNGW6VTK5CZZRLWLVVEOUPEQBRHI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XWSC77GS5NATI3TT7FMVPULUPXR635XQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YZVXG7OOOXCX6VIPEMLFDPIPUTFAYWPE https://security.gentoo.org/glsa/202402-07 https:// • CWE-404: Improper Resource Shutdown or Release •

XAPI open file limit DoS It is possible for an unauthenticated client on the network to cause XAPI to hit its file-descriptor limit. This causes XAPI to be unable to accept new requests for other (trusted) clients, and blocks XAPI from carrying out any tasks that require the opening of file descriptors. Es posible que un cliente no autenticado en la red cause que XAPI alcance su límite de descriptores de archivo. Esto causa que XAPI no pueda aceptar nuevas peticiones de otros clientes (confiables), y bloquea a XAPI de llevar a cabo cualquier tarea que requiera la apertura de descriptores de archivo • http://www.openwall.com/lists/oss-security/2022/10/11/4 http://xenbits.xen.org/xsa/advisory-413.html https://security.gentoo.org/glsa/202402-07 https://xenbits.xenproject.org/xsa/advisory-413.txt • CWE-770: Allocation of Resources Without Limits or Throttling •

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. • http://www.openwall.com/lists/oss-security/2022/10/11/2 http://xenbits.xen.org/xsa/advisory-411.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TJOMUNGW6VTK5CZZRLWLVVEOUPEQBRHI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XWSC77GS5NATI3TT7FMVPULUPXR635XQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YZVXG7OOOXCX6VIPEMLFDPIPUTFAYWPE https://security.gentoo.org/glsa/202402-07 https:// • CWE-755: Improper Handling of Exceptional Conditions •

insufficient TLB flush for x86 PV guests in shadow mode For migration as well as to work around kernels unaware of L1TF (see XSA-273), PV guests may be run in shadow paging mode. To address XSA-401, code was moved inside a function in Xen. This code movement missed a variable changing meaning / value between old and new code positions. The now wrong use of the variable did lead to a wrong TLB flush condition, omitting flushes where such are necessary. Un vaciado insuficiente del TLB para huéspedes x86 PV en modo de sombra Para la migración, así como para trabajar en torno a los kernels que no son conscientes de L1TF (véase XSA-273), los huéspedes PV pueden ejecutarse en modo de paginación de sombra. • http://www.openwall.com/lists/oss-security/2022/07/26/2 http://www.openwall.com/lists/oss-security/2022/07/26/3 http://xenbits.xen.org/xsa/advisory-408.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HUFIMNGYP5VQAA6KE3T2I5GW6UP6F7BS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MYI3OMJ7RIZNL3C6GUWNANNPEUUID6FM https://www.debian.org/security/2022/dsa-5272 https://xenbits.xenproject.org/xsa/advisory-408.txt •
