CVE-2026-89921 KVM: s390: Zero initialize data structures for inject_pfault_token

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Zero initialize data structures for injectpfaulttoken kvminjectpfaulttoken only sets .type and .u.ext.extparams2 of the on-stack struct kvms390irq but the full ext substructure is copied into the cpu local variable on...

CVE-2026-89921

CVE-2026-89921 affects the Linux kernel KVM s390 architecture. The function __kvm_inject_pfault_token() only sets .type and .u.ext.ext_params2 of the on-stack struct kvm_s390_irq, but the full ext substructure is copied into the CPU local variable on injection, leaving ext_params and pad with sta...

CVE-2026-89920

CVE-2026-89920 affects the Linux kernel's KVM s390 subsystem. The vulnerability arises when channel-subsystem damage (CK) machine checks are unnecessarily reinjected into a guest VM, even though the guest channel subsystem is emulated in the userspace VMM. This reinjection causes a kfree of a sta...

CVE-2026-89910

CVE-2026-89910 affects the Linux kernel on LoongArch architecture within the KVM subsystem. The vulnerable component is the stack variable vector[] in the function dmsintc_inject_irq() , which is sometimes used without being initialized, potentially leading to information disclosure (uninitialize...

CVE-2026-89903

CVE-2026-89903 affects the Linux kernel on the LoongArch architecture, specifically the rethook trampoline (previously the kretprobe trampoline since v6.3 ). The trampoline incorrectly saves and restores $r21 (the per-CPU base register) across its entry/exit frame. If a task migrates CPUs between...
