SUSE CVE-2026-64413

In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: zero chainstack array sashiko reports: looking at ebtables table translation, could a sparse cpupossiblemask lead to an uninitialized pointer free? If cpupossiblemask is sparse for example, CPU 0 and CPU 2 ar...

CVE-2026-64513

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Unconditionally recompute CR8 intercept on PPR update The TPRTHRESHOLD field in the VMCS is used by VMX to induce VM exits when the guest's virtual TPR falls under the specified threshold, allowing KVM to inject...

CVE-2026-64307

In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Do not initialize SNP for ioctlSNPCONFIG Sashiko notes: if SEV initialization fails and KVM is actively running normal VMs, could a userspace process trigger this code path via /dev/sev ioctls e.g., SEVPDHGEN and ze...

UBUNTU-CVE-2026-64373

In the Linux kernel, the following vulnerability has been resolved: cpufreq: Fix hotplug-suspend race during reboot During system reboot, cpufreqsuspend is called via the kernelrestart - deviceshutdown path. Unlike the normal system suspend path, the reboot path does not call freezeprocesses, so...

UBUNTU-CVE-2026-64512

In the Linux kernel, the following vulnerability has been resolved: ACPI: CPPC: Suppress UBSAN warning caused by field misuse The definition of reg-accesswidth changes depending on the reg-spaceid type. Type ACPIADRSPACEPLATFORMCOMM uses accesswidth to indicate the PCC region, which can result in...

CVE-2026-64477

In the Linux kernel, the following vulnerability has been resolved: x86,fs/resctrl: Prevent out-of-bounds access while offlining CPU when SNC enabled The architecture updates the cpumask in a domain's header to track which online CPUs are associated with the domain. When this mask becomes empty t...

CVE-2026-64374 sched/rt: Have RT_PUSH_IPI be default off for non PREEMPT_RT

In the Linux kernel, the following vulnerability has been resolved: sched/rt: Have RTPUSHIPI be default off for non PREEMPTRT RT migration is done aggressively. When a CPU schedules out a high priority RT task for a lower priority task, it will look to see if there's any RT tasks that are waiting...

CVE-2026-64374

CVE-2026-64374 concerns the Linux kernel’s RT scheduling path. The vulnerability stems from making RT_PUSH_IPI default off for non-PREEMPT_RT configurations, which could affect RT migration when high-priority RT tasks are scheduled across CPUs. The mechanism normally pulls RT tasks between CPUs u...

CVE-2026-64373

CVE-2026-64373 is a race condition in the Linux kernel cpufreq subsystem. During system reboot, cpufreq_suspend() is invoked via the kernel_restart() → device_shutdown() path without first calling freeze_processes(), allowing CPU hotplug operations to run concurrently. This can cause governor_dat...

CVE-2026-64302 x86/mm: Fix freeing of PMD-sized vmemmap pages

In the Linux kernel, the following vulnerability has been resolved: x86/mm: Fix freeing of PMD-sized vmemmap pages Commit bf9e4e30f353 "x86/mm: use pagetablefree", switched from freeing non-boot page tables through freepages to pagetablefree. However, the function is also called to free vmemmap...

CVE-2026-64290

In the Linux kernel, the following vulnerability has been resolved: iommufd: Break the loop on failure in iommufdfaultfopsread On a copytouser failure inside the inner listforeachentry, only the inner loop breaks; the outer while re-fetches the just-restored fault group and retries the failing...

CVE-2026-64286

CVE-2026-64286 affects the Linux kernel’s KVM on arm64. The vulnerability arises in flush_hyp_vcpu(): it copies the host vCPU context into the hyp private vCPU on every run. The guest-context resolver (ctxt_to_vcpu()) expects a NULL __hyp_running_vcpu (only set on the host); since the host’s valu...
