| CVE-2025-14905 | 1 Redhat | 4 Directory Server, Enterprise Linux, Enterprise Linux Eus and 1 more | 2026-03-02 | 7.2 High |
| A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE). | ||||

| CVE-2023-52356 | 2 Libtiff, Redhat | 4 Libtiff, Ai Inference Server, Discovery and 1 more | 2026-02-27 | 7.5 High |
| A segment fault (SEGV) flaw was found in libtiff that could be triggered by passing a crafted tiff file to the TIFFReadRGBATileExt() API. This flaw allows a remote attacker to cause a heap-buffer overflow, leading to a denial of service. | ||||
| CVE-2026-23750 | 1 Golioth | 1 Pouch | 2026-02-27 | 8.1 High |
| Golioth Pouch version 0.1.0, prior to commit 1b2219a1, contains a heap-based buffer overflow in BLE GATT server certificate handling. server_cert_write() allocates a heap buffer of size CONFIG_POUCH_SERVER_CERT_MAX_LEN when receiving the first fragment, then appends subsequent fragments using memcpy() without verifying that sufficient capacity remains. An adjacent BLE client can send unauthenticated fragments whose combined size exceeds the allocated buffer, causing a heap overflow and crash; integrity impact is also possible due to memory corruption. | ||||
| CVE-2026-27799 | 2 Dlemstra, Imagemagick | 2 Magick.net, Imagemagick | 2026-02-27 | 4 Medium |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in the DJVU image format handler. The vulnerability occurs due to integer truncation when calculating the stride (row size) for pixel buffer allocation. The stride calculation overflows a 32-bit signed integer, resulting in an out-of-bounds memory reads. Versions 7.1.2-15 and 6.9.13-40 contain a patch. | ||||
| CVE-2026-25576 | 2 Dlemstra, Imagemagick | 2 Magick.net, Imagemagick | 2026-02-27 | 5.1 Medium |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in multiple raw image format handles. The vulnerability occurs when processing images with -extract dimensions larger than -size dimensions, causing out-of-bounds memory reads from a heap-allocated buffer. Versions 7.1.2-15 and 6.9.13-40 contain a patch. | ||||
| CVE-2025-67433 | 1 Open Tftp Server | 1 Open Tftp Server Multithreaded | 2026-02-26 | 7.5 High |
| A heap buffer overflow in the processRequest function of Open TFTP Server MultiThreaded v1.7 allows attackers to cause a Denial of Service (DoS) via a crafted DATA packet. | ||||
| CVE-2024-9632 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-02-26 | 7.8 High |
| A flaw was found in the X.org server. Due to improperly tracked allocation size in _XkbSetCompatMap, a local attacker may be able to trigger a buffer overflow condition via a specially crafted payload, leading to denial of service or local privilege escalation in distributions where the X.org server is run with root privileges. | ||||
| CVE-2025-20734 | 3 Mediatek, Mediatk, Openwrt | 18 Mt6890, Mt7615, Mt7622 and 15 more | 2026-02-26 | 4.2 Medium |
| In wlan AP driver, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: WCNCR00441507; Issue ID: MSV-4112. | ||||
| CVE-2025-20731 | 2 Mediatek, Openwrt | 10 Mt6890, Mt7615, Mt7622 and 7 more | 2026-02-26 | 5.3 Medium |
| In wlan AP driver, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege (when OceReducedNeighborReport is disabled). User interaction is not needed for exploitation. Patch ID: WCNCR00441511; Issue ID: MSV-4140. | ||||
| CVE-2025-1943 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-02-26 | 8.2 High |
| Memory safety bugs present in Firefox 135 and Thunderbird 135. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 136 and Thunderbird < 136. | ||||
| CVE-2025-21169 | 1 Adobe | 1 Substance 3d Designer | 2026-02-26 | 7.8 High |
| Substance3D - Designer versions 14.1 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. | ||||
| CVE-2025-26634 | 1 Microsoft | 19 Windows 10 1507, Windows 10 1607, Windows 10 1809 and 16 more | 2026-02-26 | 7.5 High |
