26 Jan 2023 — Guests can cause Xenstore crash via soft reset When a guest issues a "Soft Reset" (e.g. for performing a kexec) the libxl based Xen toolstack will normally perform a XS_RELEASE Xenstore operation. Due to a bug in xenstored this can result in a crash of xenstored. Any other use of XS_RELEASE will have the same impact.

09 Nov 2022 — IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. IBPB no puede evitar que las predicciones de sucursales de retorno sean especificadas por objetivos de sucursales anteriores a IBPB, lo que lleva a una posible divulgación de información. 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. • http://www.openwall.com/lists/oss-security/2022/11/10/2 •

01 Nov 2022 — Xenstore: Guests can crash xenstored Due to a bug in the fix of XSA-115 a malicious guest can cause xenstored to use a wrong pointer during node creation in an error path, resulting in a crash of xenstored or a memory corruption in xenstored causing further damage. Entering the error path can be controlled by the guest e.g. by exceeding the quota value of maximum nodes per domain.

01 Nov 2022 — 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.
