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...

Name of the Vulnerable Software and Affected Versions Xenstore affected versions not specified Description Xenstore uses XEN DOMCTL get domain state to track the appearance and disappearance of domains. The management of the bitmap supporting this operation is linked to the binding of the VIRQ DO...
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...
