CVE-2026-98729

A flaw was found in the Linux kernel. On systems utilizing specific AMD processors, improper virtual address alignment for huge page memory mappings can allow a local user to cause a Denial of Service DoS. When unmapping these misaligned memory ranges during teardown, the kernel encounters an...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 6.14. It arises because pkvminitfeaturesfromhost retrieves KVMARCHFLAGGUESTHASSVE and KVMARMVCPUSVE from the host respectively; meanwhile, pkvmvcpuinitsve checks these feature bits while vcpuhassve reads the corresponding flags. As a result,...

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Use active memslots for the per-vCPU MMIO cache KVM tags the per-vCPU MMIO cache with a memslot generation so that a memslot update invalidates cached MMIO information. Both the fill and validation paths use kvm memslot...

In the Linux kernel, the following vulnerability has been resolved: arm64: kprobes: Allow reentering kprobes while single-stepping A kprobe can be hit while another kprobe is in KPROBE HIT SS state. This can happen when tracing or perf code runs from the debug exception path while the first kprob...

In the Linux kernel, the following vulnerability has been resolved: ibmveth: h free logical LAN on open-fail after register ibmveth open registers the logical LAN, then allocates the RX buffer pools. A pool failure jumps to out free buffer pools without h free logical lan, so PHYP still owns the...
