SUSE CVE-2026-42492
Xenstore, to have an up-to-date picture of the entire system, wants to know of domains appearing and disappearing. To make this more robust, a new XENDOMCTLgetdomainstate was introduced. The management of the bitmap underlying that operation is tied into the binding of the VIRQDOMEXC virtual IRQ...

CVE-2026-42492
The Xen hypervisor is vulnerable to a flaw in Xenstore where the management of a bitmap for the new XEN_DOMCTL_get_domain_state operation is improperly tied to the binding of the VIRQ_DOM_EXC virtual IRQ. An error path in this process can tear down the bitmap even when it was never initialized, w...

UBUNTU-CVE-2026-46057
In the Linux kernel, the following vulnerability has been resolved: landlock: Fix LOGSUBDOMAINSOFF inheritance across fork hookcredtransfer only copies the Landlock security blob when the source credential has a domain. This is inconsistent with landlockrestrictself which can set LOGSUBDOMAINSOFF...
CVE-2026-46057
The connected OpenSUSE advisory for CVE-2026-46057 documents a Linux kernel Landlock issue where fork() does not preserve the Landlock security blob because hook_cred_transfer() only copies the blob when a domain exists. The fix is to unconditionally copy the Landlock credential blob to ensure su...
