SUSE CVE-2026-43315

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-2026-43265

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for x86 architectures. A local user or a malicious guest operating system could manipulate the virtual CPU vCPU state by injecting events while the vCPU is in a blocking state. This could lead to a spurious exit to userspace,...

CVE-2026-31591

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. This vulnerability allows a local user in userspace to manipulate or run a virtual CPU vCPU while its state is being synchronized during the Secure Nested Paging SNP launch process. This improper synchronization ca...
