CVE-2026-64426

A flaw was found in the Linux kernel's iouring/nop component. A local user could exploit this by submitting a specially crafted no-operation NOP request. This could lead to a file reference not being properly released, resulting in a memory leak. Over time, this memory leak could impact system...

CVE-2026-15012 Demi <= 0.0.8 - Unauthenticated Information Exposure to Arbitrary Directory Copy

The Demi – One Click Demo Import, WP Backup & Site Migration plugin for WordPress is vulnerable to Arbitrary Directory Copy in all versions up to, and including, 0.0.8 via the handlerestorestep function. This is due to missing HTTP access controls on the wp-content/uploads/demi-backup-state/...

CVE-2026-64397

A flaw was found in the Linux kernel's ksmbd kernel Server Message Block daemon component. Concurrent directory query requests using the same file handle can lead to a stack use-after-free vulnerability. This occurs because smb2querydir stores a pointer to stack-allocated data that can be...

CVE-2026-64530

CVE-2026-64530 affects the Linux kernel net/sched subsystem. The root cause is that tcf_qevent_handle() did not properly handle TC_ACT_CONSUMED, causing the skb to be returned to the caller as if classification passed, while the defragmentation engine still owned it. This led to a use-after-free ...

CVE-2026-17434

A flaw has been found in nanocoai NanoClaw up to 2.0.64. Affected is the function handleAddMcpServer of the file src/modules/self-mod/request.ts of the component addmcpserver. Executing a manipulation can lead to improper authorization. The attack may be launched remotely. The exploit has been...
