CVE-2026-98715

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Preserve TLB control i.e. pending TLB flush on failed VMRUN Don't reset the VMCB's TLB control back to "do nothing" on a failed VMRUN, as empirical testing shows that the CPU performs the requested TLB flush if and only...

CVE-2026-98715

The Linux kernel contains a vulnerability in KVM 's SVM implementation where the VMCB's TLB control (pending TLB flush) is incorrectly reset to "do nothing" upon a failed VMRUN . Because the CPU only performs the flush if VMRUN succeeds, clearing this control effectively drops the requested TLB f...

CVE-2026-98639

The Linux kernel contains a vulnerability in the KVM module related to riscv architecture. The function __kvm_riscv_nacl_hfence() incorrectly writes the Config word before updating the Page_Number and Page_Count words. This violates the SBI v3.0 specification and allows the SBI implementation or ...

CVE-2026-89930

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM nested virtualization nVMX component. KVM fails to perform necessary Translation Lookaside Buffer TLB flushes when a nested virtual machine VM entry operation fails. This can lead to an outdated TLB state, potentially allowin...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KVM: nVMX: Always flush vpid02 on first use Ensure that vpid02 is always flushed on the first use by setting lastvpid to 0 when allocating vpid02. The nestedvmxtransitiontlbflush function will always detect a VPID change upon the...

CVE-2026-19574 ARM64 MMU can assign an in-use ASID to a new memory domain, breaking user-mode memory isolation

The ARM64 MMU back-end allocated address space identifiers ASIDs for memory domains with a bare round-robin counter in archmemdomaininit arch/arm64/core/mmu.c. VMASIDBITS is 8, so only 255 ASIDs exist; once the counter wrapped, archmemdomaininit could hand an ASID to a new domain while a still-li...

USN-8906-1 linux-ibm-6.8 vulnerabilities

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer TLB invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been...

CVE-2026-89811

A flaw was found in the Linux kernel's drm/amdkfd component. This vulnerability arises from a race condition where the Micro Engine Scheduler MES fails to perform a necessary Translation Lookaside Buffer TLB invalidation after unmapping queues. This oversight allows in-flight Direct Memory Access...
