CVE-2026-43351

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for arm64 architectures. When a virtual Generic Interrupt Controller GIC is created, a failure in the vgicallocateprivateirqslocked function can leave internal data structures uninitialized. This can lead to a system crash wh...

EUVD-2026-28585

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Remove a user-triggerable WARN on nestedsvmloadcr3 succeeding Drop the WARN in svmsetnestedstate on nestedsvmloadcr3 failing as it is trivially easy to trigger from userspace by modifying CPUID after loading CR3. E.g...

CVE-2026-43315

CVE-2026-43315 involves the Linux kernel KVM nSVM warning path. Technical details across connected docs show that a user-triggerable WARN is raised in svm_set_nested_state() when nested_svm_load_cr3() succeeds, and the patch removes this WARN. The rationale is that userspace can easily trigger th...

CVE-2026-25077

Apache CloudStack is vulnerable to an unauthenticated command injection due to missing file name sanitization when users register templates for direct download to primary storage for KVM hypervisor deployments. An attacker can register malicious templates to execute arbitrary code on KVM hosts, p...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of vgicallocateprivateirqslocked in the KVM ARM64 virtual GIC, causing it to exit...

Linux Distros Unpatched Vulnerability : CVE-2026-43315

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - KVM: nSVM: Remove a user-triggerable WARN on nestedsvmloadcr3 succeeding Drop the WARN in svmsetnestedstate on nestedsvmloadcr3 failing as it is trivially easy...

kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker with privileges on the host system could exploit a vulnerability in how KVM handles shadow page table entries SPTEs during memory-mapped I/O MMIO operations. By manipulating guest page table entrie...

Harvester's SUSE Virtualization Registration Client Vulnerable to MITM and DOS
