CVE-2026-98637 KVM: arm64: Do not clear VM-wide SVE feature on vCPU init failure

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Do not clear VM-wide SVE feature on vCPU init failure pkvmvcpuinitsve clears KVMARMVCPUSVE in kvm-arch.vcpufeatures when it fails, but vcpuhassve tests KVMARCHFLAGGUESTHASSVE, which is left set.

CVE-2026-98637

The Linux kernel contains a vulnerability in the KVM subsystem for arm64 architecture. During vCPU initialization , the function pkvm_vcpu_init_sve() incorrectly clears KVM_ARM_VCPU_SVE in kvm->arch.vcpu_features upon failure, while leaving KVM_ARCH_FLAG_GUEST_HAS_SVE set. This causes subseque...

EUVD-2026-103663

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Handle maximum standalone channels Standalone channels use one NAPI vector for each Tx and Rx queue. fbnic's allocation path excludes FBNICMAXTXQS from that layout. A 64-Tx/64-Rx configuration therefore records 128...

CVE-2026-98618

The Linux kernel contains a vulnerability in the fbnic driver related to standalone channels. The issue arises because the driver's allocation path excludes FBNIC_MAX_TXQS from the layout. In a 64-Tx/64-Rx configuration, the system records 128 vectors but only allocates 64, resulting in NULL entr...

CVE-2026-98616 eth: fbnic: reset num_napi when the napi vectors are freed

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: reset numnapi when the napi vectors are freed fbn-numnapi is the count of live napi vectors, each of which owns an IRQ. The PM path had freed them without clearing the count. fbnicpmsuspend tears the datapath down via...

CVE-2026-98616

The Linux kernel contains a vulnerability in the fbnic driver where the num_napi counter is not cleared when napi vectors are freed during power management (PM) operations. Specifically, fbnic_pm_suspend() frees IRQs without resetting the count, and certain failure scenarios—such as failed PCIe e...
