CVE-2026-34743 2 Tukaani, Tukaani-project 2 Xz, Xz 2026-04-15 5.3 Medium
XZ Utils provide a general-purpose data-compression library plus command-line tools. Prior to version 5.8.3, if lzma_index_decoder() was used to decode an Index that contained no Records, the resulting lzma_index was left in a state where where a subsequent lzma_index_append() would allocate too little memory, and a buffer overflow would occur. This issue has been patched in version 5.8.3.
CVE-2026-27301 2 Adobe, Microsoft 2 Framemaker, Windows 2026-04-15 5.5 Medium
Adobe Framemaker versions 2022.8 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could lead to memory exposure. An attacker could leverage this vulnerability to disclose sensitive information stored in memory. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2026-2447 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-04-15 8.8 High
Heap buffer overflow in libvpx. This vulnerability was fixed in Firefox 147.0.4, Firefox ESR 140.7.1, Firefox ESR 115.32.1, Thunderbird 140.7.2, and Thunderbird 147.0.2.
CVE-2026-3845 1 Mozilla 1 Firefox 2026-04-15 8.8 High

CVE-2026-4152 1 Gimp 1 Gimp 2026-04-15 7.8 High
GIMP JP2 File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of JP2 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28863.
CVE-2026-4153 1 Gimp 1 Gimp 2026-04-15 7.8 High
GIMP PSP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PSP files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28874.
CVE-2025-48990 2026-04-15 N/A
NeKernal is a free and open-source operating system stack. Version 0.0.2 has a 1-byte heap overflow in `rt_copy_memory`, which unconditionally wrote a null terminator at `dst[len]`. When `len` equals the size of the destination buffer (256 bytes), that extra `'\0'` write overruns the buffer by one byte. To avoid breaking existing callers or changing the public API, the patch in commit fb7b7f658327f659c6a6da1af151cb389c2ca4ee takes a minimal approach: it simply removes the overflow-causing line without adding bounds checks or altering the function signature.
CVE-2024-21947 1 Amd 8 Athlon, Athlon 3000, Ryzen and 5 more 2026-04-15 7.5 High
Improper input validation in the system management mode (SMM) could allow a privileged attacker to overwrite arbitrary memory potentially resulting in arbitrary code execution at the SMM level.
CVE-2025-5942 1 Netskope 1 Netskope 2026-04-15 N/A
Netskope was notified about a potential gap in its agent (NS Client) on Windows systems. If this gap is successfully exploited, an unprivileged user can trigger a heap overflow in the epdlpdrv.sys driver, leading to a Blue-Screen-of-Death (BSOD). Successful exploitation can also potentially be performed by an unprivileged user whose NS Client is configured to use Endpoint DLP. A successful exploit can result in a denial-of-service for the local machine.
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-2025-23123 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-2024-37310 1 Everest 1 Everest-core 2026-04-15 9.1 Critical
EVerest is an EV charging software stack. An integer overflow in the "v2g_incoming_v2gtp" function in the v2g_server.cpp implementation can allow a remote attacker to overflow the process' heap. This vulnerability is fixed in 2024.3.1 and 2024.6.0.
CVE-2025-55286 2026-04-15 N/A
z2d is a pure Zig 2D graphics library. z2d v0.7.0 released with a new multi-sample anti-aliasing (MSAA) method, which uses a new buffering mechanism for storing coverage data. This differs from the standard alpha mask surface used for the previous super-sample anti-aliasing (SSAA) method. Under certain circumstances where the path being drawn existed in whole or partly outside of the rendering surface, incorrect bounding could cause out-of-bounds access within the coverage buffer. This affects the higher-level drawing operations, such as Context.fill, Context.stroke, painter.fill, and painter.stroke, when either the .default or .multisample_4x anti-aliasing modes were used. .supersample_4x was not affected, nor was drawing without anti-aliasing. In non-safe optimization modes (consumers compiling with ReleaseFast or ReleaseSmall), this could potentially lead to invalid memory accesses or corruption. z2d v0.7.1 fixes this issue, and it's recommended to upgrade to v0.7.1, or, given the small period of time v0.7.0 has been released, use v0.7.1 immediately, skipping v0.7.0.
