| CVE-2026-41499 | 1 Wazuh | 1 Wazuh | 2026-06-17 | N/A | 6.5 MEDIUM |
| Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 4.0.0 to before version 4.14.4, multiple heap-based out-of-bounds WRITE vulnerabilities exist in parse_uname_string() (remoted_op.c). This function processes OS identification data from agents and contains a dangerous code pattern that appears in 4 locations within the same function: writing to strlen(ptr) - 1 without checking for empty strings. When the string is empty, strlen() returns 0, and 0 - 1 wraps to SIZE_MAX due to unsigned integer underflow. Due to pointer arithmetic wrapping, SIZE_MAX effectively becomes -1, causing a write exactly 1 byte before the allocated buffer. This corrupts heap metadata (e.g., the chunk size field in glibc malloc), leading to heap corruption. This issue has been patched in version 4.14.4. | |||||
| CVE-2026-28419 | 1 Vim | 1 Vim | 2026-06-17 | N/A | 5.3 MEDIUM |
| Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file where a delimiter appears at the start of a line, Vim attempts to read memory immediately preceding the allocated buffer. Version 9.2.0075 fixes the issue. | |||||
| CVE-2026-26204 | 1 Wazuh | 1 Wazuh | 2026-06-17 | N/A | 4.4 MEDIUM |
| Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 1.0.0 to before version 4.14.4, a heap-based out-of-bounds WRITE occurs in GetAlertData, resulting in writing a NULL byte exactly 1 byte before the start of the buffer allocated by strdup. Due to unsigned integer underflow and pointer arithmetic wrapping, the write lands at offset -1 from the buffer, corrupting heap metadata. A malicious actor can potentially leverage this issue through a compromised agent to cause denial of service or heap corruption by injecting a specially crafted alert into the alerts log file monitored by wazuh-logcollector. This issue has been patched in version 4.14.4. | |||||
| CVE-2026-1485 | 2026-06-17 | N/A | 2.8 LOW | ||
| A flaw was found in Glib's content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability. | |||||
| CVE-2025-53101 | 1 Imagemagick | 1 Imagemagick | 2026-06-17 | N/A | 7.4 HIGH |
| ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-0 and 6.9.13-26, in ImageMagick's `magick mogrify` command, specifying multiple consecutive `%d` format specifiers in a filename template causes internal pointer arithmetic to generate an address below the beginning of the stack buffer, resulting in a stack overflow through `vsnprintf()`. Versions 7.1.2-0 and 6.9.13-26 fix the issue. | |||||

| In Bluetooth FW, there is a possible system crash due to an uncaught exception. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS09752821; Issue ID: MSV-3342. | |||||
| CVE-2024-52990 | 3 Adobe, Apple, Microsoft | 3 Animate, Macos, Windows | 2026-06-17 | N/A | 7.8 HIGH |
| Animate versions 23.0.8, 24.0.5 and earlier are affected by a Buffer Underwrite ('Buffer Underflow') vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could leverage this vulnerability to manipulate memory in such a way that they could execute code under the privileges of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. | |||||
| CVE-2024-36310 | 2026-06-17 | N/A | N/A | ||
| Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity. | |||||
| CVE-2023-48230 | 1 Capnproto | 1 Capnproto | 2026-06-17 | N/A | 5.9 MEDIUM |
| Cap'n Proto is a data interchange format and capability-based RPC system. In versions 1.0 and 1.0.1, when using the KJ HTTP library with WebSocket compression enabled, a buffer underrun can be caused by a remote peer. The underrun always writes a constant value that is not attacker-controlled, likely resulting in a crash, enabling a remote denial-of-service attack. Most Cap'n Proto and KJ users are unlikely to have this functionality enabled and so unlikely to be affected. Maintainers suspect only the Cloudflare Workers Runtime is affected. If KJ HTTP is used with WebSocket compression enabled, a malicious peer may be able to cause a buffer underrun on a heap-allocated buffer. KJ HTTP is an optional library bundled with Cap'n Proto, but is not directly used by Cap'n Proto. WebSocket compression is disabled by default. It must be enabled via a setting passed to the KJ HTTP library via `HttpClientSettings` or `HttpServerSettings`. The bytes written out-of-bounds are always a specific constant 4-byte string `{ 0x00, 0x00, 0xFF, 0xFF }`. Because this string is not controlled by the attacker, maintainers believe it is unlikely that remote code execution is possible. However, it cannot be ruled out. This functionality first appeared in Cap'n Proto 1.0. Previous versions are not affected. This issue is fixed in Cap'n Proto 1.0.1.1. | |||||
| CVE-2023-34351 | 1 Intel | 1 Performance Counter Monitor | 2026-06-17 | N/A | 7.5 HIGH |
| Buffer underflow in some Intel(R) PCM software before version 202307 may allow an unauthenticated user to potentially enable denial of service via network access. | |||||
| CVE-2023-32614 | 1 Accusoft | 1 Imagegear | 2026-06-17 | N/A | 7.0 HIGH |
| A heap-based buffer overflow vulnerability exists in the create_png_object functionality of Accusoft ImageGear 20.1. A specially crafted malformed file can lead to memory corruption. An attacker can provide a malicious file to trigger this vulnerability. | |||||
| CVE-2023-31130 | 3 C-ares Project, Debian, Fedoraproject | 3 C-ares, Debian Linux, Fedora | 2026-06-17 | N/A | 4.1 MEDIUM |
| c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1. | |||||
| CVE-2023-25610 | 1 Fortinet | 8 Fortianalyzer, Fortimanager, Fortios and 5 more | 2026-06-17 | N/A | 9.8 CRITICAL |
| A buffer underwrite ('buffer underflow') vulnerability in the administrative interface of Fortinet FortiOS version 7.2.0 through 7.2.3, version 7.0.0 through 7.0.6, version 6.4.0 through 6.4.11 and version 6.2.12 and below, FortiProxy version 7.2.0 through 7.2.2, version 7.0.0 through 7.0.8, version 2.0.12 and below and FortiOS-6K7K version 7.0.5, version 6.4.0 through 6.4.10 and version 6.2.0 through 6.2.10 and below allows a remote unauthenticated attacker to execute arbitrary code or commands via specifically crafted requests. | |||||
| CVE-2022-33896 | 1 Hancom | 1 Hancom Office 2020 | 2026-06-17 | N/A | 7.8 HIGH |
| A buffer underflow vulnerability exists in the way Hword of Hancom Office 2020 version 11.0.0.5357 parses XML-based office files. A specially-crafted malformed file can cause memory corruption by using memory before buffer start, which can lead to code execution. A victim would need to access a malicious file to trigger this vulnerability. | |||||
| CVE-2022-20683 | 1 Cisco | 1 Ios Xe | 2026-06-17 | 7.8 HIGH | 8.6 HIGH |
| A vulnerability in the Application Visibility and Control (AVC-FNF) feature of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient packet verification for traffic inspected by the AVC feature. An attacker could exploit this vulnerability by sending crafted packets from the wired network to a wireless client, resulting in the crafted packets being processed by the wireless controller. A successful exploit could allow the attacker to cause a crash and reload of the affected device, resulting in a DoS condition. | |||||
