CVE-2025-23123 2026-04-15 N/A
A malicious actor with access to the management network could execute a remote code execution (RCE) by exploiting a heap buffer overflow vulnerability in the UniFi Protect Cameras (Version 4.75.43 and earlier) firmware.
CVE-2024-21885 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2026-04-15 7.8 High
A flaw was found in X.Org server. In the XISendDeviceHierarchyEvent function, it is possible to exceed the allocated array length when certain new device IDs are added to the xXIHierarchyInfo struct. This can trigger a heap buffer overflow condition, which may lead to an application crash or remote code execution in SSH X11 forwarding environments.
CVE-2025-3713 2026-04-15 7.5 High
The LCD KVM over IP Switch CL5708IM has a Heap-based Buffer Overflow vulnerability in firmware versions prior to v2.2.215, allowing unauthenticated remote attackers to exploit this vulnerability to perform a denial-of-service attack.
CVE-2025-11947 1 Bftpd 1 Bftpd 2026-04-15 4.5 Medium
A weakness has been identified in bftpd up to 6.2. Impacted is the function expand_groups of the file options.c of the component Configuration File Handler. Executing a manipulation can lead to heap-based buffer overflow. It is possible to launch the attack on the local host. Attacks of this nature are highly complex. The exploitability is considered difficult. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2025-46333 2026-04-15 N/A
z2d is a pure Zig 2D graphics library. Versions of z2d after `0.5.1` and up to and including `0.6.0`, when writing from one surface to another using `z2d.compositor.StrideCompositor.run`, and higher-level operations when the anti-aliasing mode is set to `.default` (such as `Context.fill`, `Context.stroke`, `painter.fill`, and `painter.stroke`), the source surface can be completely out-of-bounds on the x-axis, but not on the y-axis, by way of a negative offset. This results in an overflow of the value controlling the length of the stride. In non-safe optimization modes (consumers compiling with `ReleaseFast` or `ReleaseSmall`), this could potentially lead to invalid memory accesses or corruption. This issue is patched in version `0.6.1`. Users on an untagged version after `v0.5.1` and before `v0.6.1` are advised to update to address the vulnerability. Those still on Zig `0.13.0` are recommended to downgrade to `v0.5.1`.
CVE-2025-29069 2026-04-15 7.3 High
A heap buffer overflow vulnerability has been identified in the lcms2-2.16. The vulnerability exists in the UnrollChunkyBytes function in cmspack.c, which is responsible for handling color space transformations. NOTE: this is disputed by the Supplier because the finding identified a bug in a third-party calling program, not in lcms.
CVE-2025-29070 2026-04-15 7.5 High
A heap buffer overflow vulnerability has been identified in thesmooth2() in cmsgamma.c in lcms2-2.16 which allows a remote attacker to cause a denial of service. NOTE: the Supplier disputes this because "this is not exploitable as this function is never called on normal color management, is there only as a helper for low-level programming and investigation."
CVE-2025-10504 1 Abb 1 Terra Ac Wallbox Jp 2026-04-15 6.1 Medium
Heap-based Buffer Overflow vulnerability in ABB Terra AC wallbox.This issue affects Terra AC wallbox: through 1.8.33.
CVE-2023-31343 2026-04-15 7.5 High
Improper input validation in the SMM handler may allow a privileged attacker to overwrite SMRAM, potentially leading to arbitrary code execution.
CVE-2024-0145 2026-04-15 6.8 Medium
NVIDIA nvJPEG2000 library contains a vulnerability where an attacker can cause a heap-based buffer overflow issue by means of a specially crafted JPEG2000 file. A successful exploit of this vulnerability might lead to code execution and data tampering.
CVE-2019-25327 2 Mersenne, Mersenne Research, Inc 2 Prime95, Prime95 2026-04-15 9.8 Critical
Prime95 version 29.8 build 6 contains a buffer overflow vulnerability in the user ID input field that allows remote attackers to execute arbitrary code. Attackers can craft a malicious payload and paste it into the PrimeNet user ID and proxy host fields to trigger a bind shell on port 3110.
CVE-2025-61553 1 Bitvisor 1 Bitvisor 2026-04-15 8.2 High
An out-of-bounds write in VirtIO network device emulation in BitVisor from commit 108df6 (2020-05-20) to commit 480907 (2025-07-06) allows local attackers to cause a denial of service (host hypervisor crash) via a crafted PCI configuration space access. Given it's a heap overflow in a privileged hypervisor context, exploitation may enable arbitrary code execution or guest-to-host privilege escalation.
CVE-2019-15690 1 Redhat 2 Enterprise Linux, Rhel E4s 2026-04-15 8.8 High
LibVNCServer 0.9.12 release and earlier contains heap buffer overflow vulnerability within the HandleCursorShape() function in libvncclient/cursor.c. An attacker sends cursor shapes with specially crafted dimensions, which can result in remote code execution.

A vulnerability was found in sparklemotion nokogiri c29c920907366cb74af13b4dc2230e9c9e23b833 and classified as problematic. This issue affects the function hashmap_set_with_hash of the file gumbo-parser/src/hashmap.c. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The identifier of the patch is ada4708e5a67114402cd3feb70a4e1d1d7cf773a. It is recommended to apply a patch to fix this issue. The project maintainer explains that the affected code was merged into the main branch but the commit never appeared in an official release.
CVE-2024-43802 1 Vim 1 Vim 2026-04-15 4.5 Medium
Vim is an improved version of the unix vi text editor. When flushing the typeahead buffer, Vim moves the current position in the typeahead buffer but does not check whether there is enough space left in the buffer to handle the next characters. So this may lead to the tb_off position within the typebuf variable to point outside of the valid buffer size, which can then later lead to a heap-buffer overflow in e.g. ins_typebuf(). Therefore, when flushing the typeahead buffer, check if there is enough space left before advancing the off position. If not, fall back to flush current typebuf contents. It's not quite clear yet, what can lead to this situation. It seems to happen when error messages occur (which will cause Vim to flush the typeahead buffer) in comnination with several long mappgins and so it may eventually move the off position out of a valid buffer size. Impact is low since it is not easily reproducible and requires to have several mappings active and run into some error condition. But when this happens, this will cause a crash. The issue has been fixed as of Vim patch v9.1.0697. Users are advised to upgrade. There are no known workarounds for this issue.
CVE-2025-64693 2 Intercom, Microsoft 2 Malion, Windows 2026-04-15 N/A
Security Point (Windows) of MaLion and MaLionCloud contains a heap-based buffer overflow vulnerability in processing Content-Length. Receiving a specially crafted request from a remote unauthenticated attacker could lead to arbitrary code execution with SYSTEM privilege.
