CVE-2026-72692

A missing authorization vulnerability in OpenSignLabs opensignserver through 2.37.0 allows an unauthenticated remote attacker to irreversibly decline any in-flight document and forge the decline attribution to an arbitrary user via the declinedoc Parse cloud function. The function writes...

CVE-2026-68200

In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: don't re-enter an instance callback that is still running The userspace-driven timer utimer TRIGGER ioctl calls sndtimerinterrupt directly with no serialization, so two threads triggering the same utimer can run...

CVE-2026-68384

CVE-2026-68384 pertains to the Linux kernel component drm/xe/vf, where race conditions were found in VF CCS attach/detach behavior during in-flight BO moves and VF migration. The issue arises because xe_bo_move() attached CCS read/write batch buffers to a BO after it transitioned NULL/SYSTEM → TT...

CVE-2026-68201

The CVE-2026-68201 issue affects the Linux kernel ALSA timer: when closing a master timer, a slave’s in-flight callback may run after detach, causing use-after-free. The fix drains slave callbacks before removing slave links, and stops pending/active callbacks on the slave side before freeing. Th...

CVE-2026-70483

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.6 until 0.11.0, DELETE /api/v1/chats/id cancelled a chat's in-flight tasks before checking whether the caller could delete that chat. Any authenticated user who knew another user's chat id could abort...

GHSA-3VF6-64VR-3G56 Open WebUI: Any authenticated user can cancel another user's chat generation via the chat delete endpoint

Summary DELETE /api/v1/chats/id cancelled a chat's in-flight tasks before it checked whether the caller was allowed to delete that chat. Any authenticated user who knew another user's chat id could therefore abort that user's running model response, title generation or tag generation. The deletio...
