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-2025-36854 1 Microsoft 1 .net 2026-04-15 8.1 High
A vulnerability ( CVE-2024-38229 https://www.cve.org/CVERecord ) exists in EOL ASP.NET when closing an HTTP/3 stream while application code is writing to the response body, a race condition may lead to use-after-free, resulting in Remote Code Execution. Per CWE-416: Use After Free https://cwe.mitre.org/data/definitions/416.html , Use After Free is when a product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. This issue affects EOL ASP.NET 6.0.0 <= 6.0.36 as represented in this CVE, as well as 8.0.0 <= 8.0.8, 9.0.0-preview.1.24081.5 <= 9.0.0.RC.1 as represented in  CVE-2024-38229 https://www.cve.org/CVERecord . Additionally, if you've deployed self-contained applications https://docs.microsoft.com/dotnet/core/deploying/#self-contained-deployments-scd  targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed. NOTE: This CVE only represents End Of Life (EOL) software components. The vendor, Microsoft, has indicated there will be no future updates nor support provided upon inquiry.
CVE-2024-40885 1 Intel 1 M20ntp Firmware 2026-04-15 7.5 High
Use after free in the UEFI firmware of some Intel(R) Server M20NTP BIOS may allow a privileged user to potentially enable escalation of privilege via local access.
CVE-2025-10729 1 Qt 1 Qt 2026-04-15 8.6 High
The module will parse a <pattern> node which is not a child of a structural node. The node will be deleted after creation but might be accessed later leading to a use after free.
CVE-2024-31083 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-04-15 7.8 High
A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. This issue occurs when AllocateGlyph() is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently, ProcRenderAddGlyphs() may free a glyph, leading to a use-after-free scenario when the same glyph pointer is subsequently accessed. This flaw allows an authenticated attacker to execute arbitrary code on the system by sending a specially crafted request.
CVE-2025-0622 1 Redhat 2 Enterprise Linux, Openshift 2026-04-15 6.4 Medium
A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to a use-after-free vulnerability. If correctly exploited, this vulnerability may result in arbitrary code execution, eventually allowing the attacker to bypass secure boot protections.
CVE-2025-25177 1 Imaginationtech 1 Graphics Ddk 2026-04-15 5.1 Medium
Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger use-after-free kernel exceptions.
CVE-2024-9979 1 Redhat 2 Ansible Automation Platform, Enterprise Linux 2026-04-15 5.3 Medium
A flaw was found in PyO3. This vulnerability causes a use-after-free issue, potentially leading to memory corruption or crashes via unsound borrowing from weak Python references.
CVE-2025-3416 1 Redhat 5 Directory Server, Enterprise Linux, Openshift and 2 more 2026-04-15 3.7 Low
A flaw was found in OpenSSL's handling of the properties argument in certain functions. This vulnerability can allow use-after-free exploitation, which may result in undefined behavior or incorrect property parsing, leading to OpenSSL treating the input as an empty string.
CVE-2024-43701 1 Imaginationtech 1 Graphics Ddk 2026-04-15 7.8 High
Software installed and run as a non-privileged user may conduct GPU system calls to read and write freed physical memory from the GPU.
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-2025-33220 1 Nvidia 6 Geforce, Quadro, Rtx and 3 more 2026-04-15 7.8 High
NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager, where a malicious guest could cause heap memory access after the memory is freed. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, or information disclosure.
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.
