CVE-2026-31684

The CVE-2026-31684 issue is in the Linux kernel’s net/sched pathology (act_csum) where tcf_csum_act() reads nested VLAN headers directly from skb->data if the payload contains VLAN tags, and may read VLAN_HLEN bytes before guaranteeing the full header is present. The root cause is that the cod...

CVE-2026-31593

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine virtualization module. When Secure Nested Paging SNP is enabled, an attempt to update the state of an already running and encrypted virtual machine can cause the host system to crash. This vulnerability leads to a Denial of...

CVE-2026-31591

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. This vulnerability allows a local user in userspace to manipulate or run a virtual CPU vCPU while its state is being synchronized during the Secure Nested Paging SNP launch process. This improper synchronization ca...

CVE-2026-42039

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, toFormData recursively walks nested objects with no depth limit, so a deeply nested value passed as request data crashes the Node.js process with a RangeError. This vulnerability is fixed in 1.15.1 and...
