| CVE-2025-11677 | 1 Warmcat | 1 Libwebsockets | 2026-04-15 | 3.7 Low |
| Use After Free in WebSocket server implementation in lws_handshake_server in warmcat libwebsockets may allow an attacker, in specific configurations where the user provides a callback function that handles LWS_CALLBACK_HTTP_CONFIRM_UPGRADE, to achieve denial of service. | ||||
| CVE-2025-9020 | 1 Dronecode | 1 Px4 Drone Autopilot | 2026-04-15 | 4.5 Medium |
| A vulnerability was found in PX4 PX4-Autopilot up to 1.15.4. This issue affects the function MavlinkReceiver::handle_message_serial_control of the file src/modules/mavlink/mavlink_receiver.cpp of the component Mavlink Shell Closing Handler. The manipulation of the argument _mavlink_shell leads to use after free. An attack has to be approached locally. The complexity of an attack is rather high. The exploitation is known to be difficult. The identifier of the patch is 4395d4f00c49b888f030f5b43e2a779f1fa78708. It is recommended to apply a patch to fix this issue. | ||||
| CVE-2024-12837 | 2026-04-15 | 7.8 High | ||
| Software installed and run as a non-privileged user may conduct improper GPU system calls to corrupt kernel heap memory. | ||||
| CVE-2011-10034 | 1 Irai | 1 Automgen | 2026-04-15 | N/A |
| AUTOMGEN versions up to and including 8.0.0.7 (also referenced as 8.022) contain a vulnerability in that project file handling frees an object and subsequently dereferences the stale pointer when processing certain malformed fields. The dangling-pointer use enables an attacker to influence an indirect call through attacker-controlled memory, resulting in denial-of-service. In some conditions, remote code execution may be possible. | ||||
| CVE-2025-40001 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 4.4 Medium |
| In the Linux kernel, the following vulnerability has been resolved: scsi: mvsas: Fix use-after-free bugs in mvs_work_queue During the detaching of Marvell's SAS/SATA controller, the original code calls cancel_delayed_work() in mvs_free() to cancel the delayed work item mwq->work_q. However, if mwq->work_q is already running, the cancel_delayed_work() may fail to cancel it. This can lead to use-after-free scenarios where mvs_free() frees the mvs_info while mvs_work_queue() is still executing and attempts to access the already-freed mvs_info. A typical race condition is illustrated below: CPU 0 (remove) | CPU 1 (delayed work callback) mvs_pci_remove() | mvs_free() | mvs_work_queue() cancel_delayed_work() | kfree(mvi) | | mvi-> // UAF Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure that the delayed work item is properly canceled and any executing delayed work item completes before the mvs_info is deallocated. This bug was found by static analysis. | ||||
| CVE-2024-46973 | 2026-04-15 | 7.8 High | ||

| CVE-2025-31498 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2026-04-15 | 7.0 High |
| c-ares is an asynchronous resolver library. From 1.32.3 through 1.34.4, there is a use-after-free in read_answers() when process_answer() may re-enqueue a query either due to a DNS Cookie Failure or when the upstream server does not properly support EDNS, or possibly on TCP queries if the remote closed the connection immediately after a response. If there was an issue trying to put that new transaction on the wire, it would close the connection handle, but read_answers() was still expecting the connection handle to be available to possibly dequeue other responses. In theory a remote attacker might be able to trigger this by flooding the target with ICMP UNREACHABLE packets if they also control the upstream nameserver and can return a result with one of those conditions, this has been untested. Otherwise only a local attacker might be able to change system behavior to make send()/write() return a failure condition. This vulnerability is fixed in 1.34.5. | ||||
| CVE-2025-52885 | 1 Poppler | 1 Poppler | 2026-04-15 | 6.2 Medium |
| Poppler ia a library for rendering PDF files, and examining or modifying their structure. A use-after-free (write) vulnerability has been detected in versions Poppler prior to 25.10.0 within the StructTreeRoot class. The issue arises from the use of raw pointers to elements of a `std::vector`, which can lead to dangling pointers when the vector is resized. The vulnerability stems from the way that refToParentMap stores references to `std::vector` elements using raw pointers. These pointers may become invalid when the vector is resized. This vulnerability is a common security problem involving the use of raw pointers to `std::vectors`. Internally, `std::vector `stores its elements in a dynamically allocated array. When the array reaches its capacity and a new element is added, the vector reallocates a larger block of memory and moves all the existing elements to the new location. At this point if any pointers to elements are stored before a resize occurs, they become dangling pointers once the reallocation happens. Version 25.10.0 contains a patch for the issue. | ||||
| CVE-2025-57109 | 1 Vtk | 1 Vtk | 2026-04-15 | 6.5 Medium |
| Kitware VTK (Visualization Toolkit) 9.5.0 is vulnerable to Heap Use-After-Free in vtkGLTFImporter::ImportActors. When processing GLTF files with invalid scene node references, the application accesses string members of mesh objects that have been previously freed during actor import operations. | ||||
