This update for xen fixes the following issues: - CVE-2023-46842: Fixed x86 HVM hypercalls may trigger Xen bug check XSA-454, bsc1221984. - CVE-2024-31143: Fixed double unlock in x86 guest IRQ handling XSA-458, bsc1227355...

double unlock in x86 guest IRQ handling

ISSUE DESCRIPTION An optional feature of PCI MSI called "Multiple Message" allows a device to use multiple consecutive interrupt vectors. Unlike for MSI-X, the setting up of these consecutive vectors needs to happen all in one go. In this handling an error path could be taken in different...
