x86: speculative vulnerability in 32bit SYSCALL path Due to an oversight in the very original Spectre/Meltdown security work (XSA-254), one entrypath performs its speculation-safety actions too late. In some configurations, there is an unprotected RET instruction which can be attacked with a variety of speculative attacks. • http://www.openwall.com/lists/oss-security/2023/03/21/3 http://xenbits.xen.org/xsa/advisory-429.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5L6PM4RE7MUE6OWA32ZVOXCP235RM2TM https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/APBMS2Q6746AXAFAITNJMGBNFGNMVLWR https://security.gentoo.org/glsa/202402-07 https://www.debian.org/security/2023/dsa-5378 https://xenbits.xenproject.org/xsa/advisory-429.txt •

x86/HVM pinned cache attributes mis-handling T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] To allow cachability control for HVM guests with passed through devices, an interface exists to explicitly override defaults which would otherwise be put in place. While not exposed to the affected guests themselves, the interface specifically exists for domains controlling such guests. This interface may therefore be used by not fully privileged entities, e.g. qemu running deprivileged in Dom0 or qemu running in a so called stub-domain. With this exposure it is an issue that - the number of the such controlled regions was unbounded (CVE-2022-42333), - installation and removal of such regions was not properly serialized (CVE-2022-42334). • http://www.openwall.com/lists/oss-security/2023/03/21/2 http://xenbits.xen.org/xsa/advisory-428.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5L6PM4RE7MUE6OWA32ZVOXCP235RM2TM https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/APBMS2Q6746AXAFAITNJMGBNFGNMVLWR https://security.gentoo.org/glsa/202402-07 https://www.debian.org/security/2023/dsa-5378 https://xenbits.xenproject.org/xsa/advisory-428.txt • CWE-770: Allocation of Resources Without Limits or Throttling •

Xenstore: Guests can create orphaned Xenstore nodes By creating multiple nodes inside a transaction resulting in an error, a malicious guest can create orphaned nodes in the Xenstore data base, as the cleanup after the error will not remove all nodes already created. When the transaction is committed after this situation, nodes without a valid parent can be made permanent in the data base. Xenstore: los invitados pueden crear nodos huérfanos de Xenstore al crear varios nodos dentro de una transacción que genera un error, un invitado malintencionado puede crear nodos huérfanos en la base de datos de Xenstore, ya que la limpieza después del error no eliminará todos los nodos ya creados. Cuando la transacción se confirma después de esta situación, los nodos sin un padre válido pueden hacerse permanentes en la base de datos. • http://www.openwall.com/lists/oss-security/2022/11/01/5 http://xenbits.xen.org/xsa/advisory-415.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YTMITQBGC23MSDHUCAPCVGLMVXIBXQTQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YZVXG7OOOXCX6VIPEMLFDPIPUTFAYWPE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZLI2NPNEH7CNJO3VZGQNOI4M4EWLNKPZ https://security.gentoo.org/glsa/202402-07 https:// • CWE-459: Incomplete Cleanup •

race in VT-d domain ID cleanup Xen domain IDs are up to 15 bits wide. VT-d hardware may allow for only less than 15 bits to hold a domain ID associating a physical device with a particular domain. Therefore internally Xen domain IDs are mapped to the smaller value range. The cleaning up of the housekeeping structures has a race, allowing for VT-d domain IDs to be leaked and flushes to be bypassed.
