CVE-2025-31946 2026-04-15 6.2 Medium
Pixmeo OsiriX MD is vulnerable to a local use after free scenario, which could allow an attacker to locally import a crafted DICOM file and cause memory corruption or a system crash.
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-2025-14569 1 Ggml 1 Whisper.cpp 2026-04-15 5.3 Medium
A vulnerability was detected in ggml-org whisper.cpp up to 1.8.2. Affected is the function read_audio_data of the file /whisper.cpp/examples/common-whisper.cpp. The manipulation results in use after free. The attack requires a local approach. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2025-55118 1 Bmc 1 Control-m/agent 2026-04-15 8.9 High
Memory corruptions can be remotely triggered in the Control-M/Agent when SSL/TLS communication is configured. The issue occurs in the following cases: * Control-M/Agent 9.0.20: SSL/TLS configuration is set to the non-default setting "use_openssl=n"; * Control-M/Agent 9.0.21 and 9.0.22: Agent router configuration uses the non-default settings "JAVA_AR=N" and "use_openssl=n"
CVE-2024-4418 1 Redhat 3 Advanced Virtualization, Enterprise Linux, Rhel Eus 2026-04-15 6.2 Medium
A race condition leading to a stack use-after-free flaw was found in libvirt. Due to a bad assumption in the virNetClientIOEventLoop() method, the `data` pointer to a stack-allocated virNetClientIOEventData structure ended up being used in the virNetClientIOEventFD callback while the data pointer's stack frame was concurrently being "freed" when returning from virNetClientIOEventLoop(). The 'virtproxyd' daemon can be used to trigger requests. If libvirt is configured with fine-grained access control, this issue, in theory, allows a user to escape their otherwise limited access. This flaw allows a local, unprivileged user to access virtproxyd without authenticating. Remote users would need to authenticate before they could access it.
CVE-2025-9157 1 Appneta 1 Tcpreplay 2026-04-15 5.3 Medium
A vulnerability was determined in appneta tcpreplay up to 4.5.2-beta2. The impacted element is the function untrunc_packet of the file src/tcpedit/edit_packet.c of the component tcprewrite. Executing manipulation can lead to use after free. It is possible to launch the attack on the local host. The exploit has been publicly disclosed and may be utilized. This patch is called 73008f261f1cdf7a1087dc8759115242696d35da. Applying a patch is advised to resolve this issue.
CVE-2025-48945 2026-04-15 5.5 Medium
pycares is a Python module which provides an interface to c-ares. c-ares is a C library that performs DNS requests and name resolutions asynchronously. Prior to version 4.9.0, pycares is vulnerable to a use-after-free condition that occurs when a Channel object is garbage collected while DNS queries are still pending. This results in a fatal Python error and interpreter crash. The vulnerability has been fixed in pycares 4.9.0 by implementing a safe channel destruction mechanism.
CVE-2024-0147 1 Nvidia 1 Gpu Display Driver 2026-04-15 5.5 Medium
NVIDIA GPU display driver for Windows and Linux contains a vulnerability where referencing memory after it has been freed can lead to denial of service or data tampering.
CVE-2024-43703 1 Imaginationtech 1 Ddk 2026-04-15 8.1 High
Software installed and run as a non-privileged user may conduct improper GPU system calls to achieve unauthorised reads and writes of physical memory from the GPU HW.
CVE-2025-65953 1 Emqx 1 Nanomq 2026-04-15 N/A
NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. Prior to version 0.22.5, a Heap-Use-After-Free (UAF) vulnerability exists in the TCP transport component of NanoMQ, which relies on the underlying NanoNNG library (specifically in src/sp/transport/mqtt/broker_tcp.c). The vulnerability is due to improper resource management and premature cleanup of message and pipe structures under specific malformed MQTTV5 retain message traffic conditions. This issue has been patched in version 0.22.5.
CVE-2025-23280 2 Linux, Nvidia 2 Linux, Display Driver 2026-04-15 7 High
NVIDIA Display Driver for Linux contains a vulnerability where an attacker could cause a use-after-free. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, and information disclosure.
CVE-2025-59734 1 Ffmpeg 1 Ffmpeg 2026-04-15 6.5 Medium
It is possible to cause an use-after-free write in SANM decoding with a carefully crafted animation using subversion <2. When a STOR chunk is present, a subsequent FOBJ chunk will be saved in ctx->stored_frame. Stored frames can later be referenced by FTCH chunks. For files using subversion < 2, the undecoded frame is stored, and decoded again when the FTCH chunks are parsed. However, in process_frame_obj if the frame has an invalid size, there’s an early return, with a value of 0.  This causes the code in decode_frame to still store the raw frame buffer into ctx->stored_frame. Leaving ctx->has_dimensions set to false. A subsequent chunk with type FTCH would call process_ftch and decode that frame obj again, adding to the top/left values and calling process_frame_obj again. Given that we never set ctx->have_dimensions before, this time we set the dimensions, calling init_buffers, which can reallocate the buffer in ctx->stored_frame, freeing the previous one. However, the GetByteContext object gb still holds a reference to the old buffer. Finally, when the code tries to decode the frame, codecs that accept a GetByteContext as a parameter will trigger a use-after-free read when using gb. GetByteContext is only used for reading bytes, so at most one could read invalid data. There are no heap allocations between the free and when the object is accessed. However, upon returning to process_ftch, the code restores the original values for top/left in stored_frame, writing 4 bytes to the freed data at offset 6, potentially corrupting the allocator’s metadata. This issue can be triggered just by probing whether a file has the sanm format. We recommend upgrading to version 8.0 or beyond.
