CVE-2026-98390

A flaw was found in the Linux kernel. When running in certain virtualized environments, an unexpected hardware topology reported by the hypervisor can cause the AMD node initialization logic to calculate a divisor of zero. This condition triggers an unhandled divide-by-zero error during system...

CVE-2026-98390

In the Linux kernel, the following vulnerability has been resolved: x86/amdnode: Avoid divide by zero on virtualized systems On a virtualized system, the number of nodes does not have a relationship to the number of roots. A Xen PVH dom0 can calculate rootspernode as 0, which crashes with a divid...

CVE-2026-98390

The Linux kernel contains a vulnerability where a divide by zero error can occur on certain virtualized systems, specifically Xen PVH dom0 . The issue arises because the underlying topology code on Xen can result in a roots_per_node value of 0 when num_nodes is 2 and num_roots is 1. This causes a...

PT-2026-114369

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A divide by zero error occurs on virtualized systems, specifically observed in Xen PVH dom0. The issue arises because the number of nodes does not necessarily relate to the number of...

CVE-2026-98164

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem. When virtualized System Management Mode SMM is enabled, memory write tracking only checks the active memory slot rather than all address spaces sharing shadow pages. An attacker inside a guest virtual machine can...

Linux Kernel Security Vulnerabilities

Versions of the Linux kernel prior to 6.12.110, 6.18.51, and 7.2.5 contain security vulnerabilities. These vulnerabilities stem from KVM’s failure to ensure that the INVVPID is executed on the same physical CPU as the last execution of L2, resulting in TLB entries not being invalidated. This coul...

Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw was discovered in the Linux kernel’s implementation of proxied virtualized TPM devices. In a system where virtualized TPM devices are enabled which is not the default setting, a local attacker can exploit this flaw to create a “use-after-free” condition, potentially allowing them to escala...

CVE-2026-79603

x86 PV guests can free memory pages while still keeping a stale TLB entry pointing to them. A TLB flush is only issued by Xen if needed when the page is re-used. Since it's possible for the page to be scrubbed ahead of the TLB flush, there's a window where a PV guest can modify an already scrubbe...

CVE-2026-45197

Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a read and/or write data outside the Guest's virtualised GPU memory. The firmware uses data provided by the Guest VM to set up accesses to memory. It validated this before use, but a...

The firmware uses data provided by the Guest VM to set up accesses to memory. It validated this before use, but a...

CVE-2026-80665

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component for ARM64 architectures. The kvmhandlevncrabort function incorrectly assumes that a specific translation result always indicates an abort, even when kvmtranslatevncr returns an error for a Guest Frame Number GFN...

CVE-2026-64106 KVM: arm64: vgic-its: Reject restored DTE with out-of-range num_eventid_bits

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Reject restored DTE with out-of-range numeventidbits Userspace can restore an ITS Device Table Entry whose Size field encodes more EventID bits than the virtual ITS supports. The live MAPD path rejects that...

PT-2026-64385

libusb before version 1.0.30 contains a NULL pointer dereference vulnerability that allows attackers to crash applications by supplying a malformed USB configuration descriptor where an interface claims bNumEndpoints greater than zero but is followed by a class-specific descriptor whose bLength...

CVE-2026-53325

In the Linux kernel, the following vulnerability has been resolved: agp/amd64: Fix broken error propagation in agpamd64probe A NULL pointer dereference was observed in the AMD64 AGP driver when running in a virtualized environment e.g. qemu/kvm without a physical AMD northbridge. The crash occurs...

SUSE CVE-2026-47104

libusb before version 1.0.30 contains a one-byte out-of-bounds read vulnerability in parseiadarray in descriptor.c that allows attackers to trigger a denial of service by supplying a malformed USB descriptor whose bLength equals size minus one, causing the bounds check to use the original buffer...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the parseiadarray function. An attacker can cause a denial of service by supplying a malformed USB descriptor with a crafted bLength value, leading to a one-byte out-of-bounds read when processing USB interface...
