HMS Networks Ewon Flexy with firmware before 15.0s4, Cosy+ with firmware 22.xx before 22.1s6, and Cosy+ with firmware 23.xx before 23.0s3 have a stack buffer overflow that leads to a Denial of Service, which can also be exploited to achieve Unauthenticated Remote Code Execution.
CVE-2026-25790 1 Wazuh 1 Wazuh 2026-06-17 N/A 4.9 MEDIUM
Wazuh is a free and open source platform used for threat prevention, detection, and response. Starting in version 3.9.0 and prior to version 4.14.3, multiple stack-based buffer overflows exist in the Security Configuration Assessment (SCA) decoder (`wazuh-analysisd`). The use of `sprintf` with a floating-point (`%lf`) format specifier on a fixed-size 128-byte buffer allows a remote attacker to overflow the stack. A specially crafted JSON event can trigger this overflow, leading to a denial of service (crash) or potential RCE on the Wazuh manager. The vulnerability is located in `/src/analysisd/decoders/security_configuration_assessment.c`, within the `FillScanInfo` and `FillCheckEventInfo` functions. In multiple locations, a 128-byte buffer (`char value[OS_SIZE_128];`) is allocated on the stack to hold the string representation of a number from a JSON event. The code checks if the number is an integer or a double. If it's a double, it uses `sprintf(value, "%lf", ...)` to perform the conversion. This `sprintf` call is unbounded. If a floating-point number with a large exponent (e.g., `1.0e150`) is provided, `sprintf` will attempt to write its full string representation (a "1" followed by 150 zeros), which is larger than the 128-byte buffer, corrupting the stack. Version 4.14.3 patches the issue.
CVE-2026-25772 1 Wazuh 1 Wazuh 2026-06-17 N/A 4.9 MEDIUM
Wazuh is a free and open source platform used for threat prevention, detection, and response. Starting in version 4.4.0 and prior to version 4.14.3, a stack-based buffer overflow vulnerability exists in the Wazuh Database synchronization module (`wdb_delta_event.c`). The SQL query construction logic allows for an integer underflow when calculating the remaining buffer size. This occurs because the code incorrectly aggregates the return value of `snprintf`. If a specific database synchronization payload exceeds the size of the query buffer (2048 bytes), the size calculation wraps around to a massive integer, effectively removing bounds checking for subsequent writes. This allows an attacker to corrupt the stack, leading to a Denial of Service (DoS) or potentially RCE. Version 4.14.3 fixes the issue.
CVE-2026-25727 1 Time Project 1 Time 2026-06-17 N/A 6.5 MEDIUM
time provides date and time handling in Rust. From 0.3.6 to before 0.3.47, when user-provided input is provided to any type that parses with the RFC 2822 format, a denial of service attack via stack exhaustion is possible. The attack relies on formally deprecated and rarely-used features that are part of the RFC 2822 format used in a malicious manner. Ordinary, non-malicious input will never encounter this scenario. A limit to the depth of recursion was added in v0.3.47. From this version, an error will be returned rather than exhausting the stack.
CVE-2026-25584 1 Color 1 Iccdev 2026-06-17 N/A 7.8 HIGH
iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.3, there is a stack-buffer-overflow vulnerability in CIccTagFloatNum<>::GetValues(). This is triggered when processing a malformed ICC profile. The vulnerability allows an out-of-bounds write on the stack, potentially leading to memory corruption, information disclosure, or code execution when processing specially crafted ICC files. This issue has been patched in version 2.3.1.3.
CVE-2026-25570 1 Siemens 1 Sicam Siapp Sdk 2026-06-17 N/A 7.4 HIGH
A vulnerability has been identified in SICAM SIAPP SDK (All versions < V2.1.7). The SICAM SIAPP SDK does not perform checks on input values potentially resulting in stack overflow. This could allow an attacker to perform code execution and denial of service.
CVE-2026-25502 1 Color 1 Iccdev 2026-06-17 N/A 7.8 HIGH
iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.2, stack-based buffer overflow in icFixXml() function when processing malformed ICC profiles, allows potential arbitrary code execution through crafted NamedColor2 tags. This issue has been patched in version 2.3.1.2.
CVE-2026-24882 2 Gnupg, Gpg4win 2 Gnupg, Gpg4win 2026-06-17 N/A 8.4 HIGH
In GnuPG before 2.5.17, a stack-based buffer overflow exists in tpm2daemon during handling of the PKDECRYPT command for TPM-backed RSA and ECC keys.
CVE-2026-24881 2 Gnupg, Gpg4win 2 Gnupg, Gpg4win 2026-06-17 N/A 8.1 HIGH
In GnuPG before 2.5.17, a crafted CMS (S/MIME) EnvelopedData message carrying an oversized wrapped session key can cause a stack-based buffer overflow in gpg-agent during PKDECRYPT--kem=CMS handling. This can easily be leveraged for denial of service; however, there is also memory corruption that could lead to remote code execution.

CVE-2026-23995 1 Linuxfoundation 1 Everest 2026-06-17 N/A 8.4 HIGH
EVerest is an EV charging software stack. Prior to version 2026.02.0, stack-based buffer overflow in CAN interface initialization: passing an interface name longer than IFNAMSIZ (16) to CAN open routines overflows `ifreq.ifr_name`, corrupting adjacent stack data and enabling potential code execution. A malicious or misconfigured interface name can trigger this before any privilege checks. Version 2026.02.0 contains a patch.
CVE-2026-23747 2026-06-17 N/A 3.7 LOW
Golioth Firmware SDK version 0.10.0 prior to 0.22.0, fixed in commit 48f521b, contain a stack-based buffer overflow in Payload Utils. The golioth_payload_as_int() and golioth_payload_as_float() helpers copy network-supplied payload data into fixed-size stack buffers using memcpy() with a length derived from payload_size. The only length checks are guarded by assert(); in release builds, the asserts are compiled out and memcpy() may copy an unbounded payload_size. Payloads larger than 12 bytes (int) or 32 bytes (float) can overflow the stack, resulting in a crash/denial of service. This is reachable via LightDB State on_payload with a malicious server or MITM.
CVE-2026-22923 1 Siemens 1 Nx 2026-06-17 N/A 7.8 HIGH
A vulnerability has been identified in NX (All versions < V2512), NX (Managed Mode) (All versions < V2512). The affected application contains a data validation vulnerability that could allow an attacker with local access to interfere with internal data during the PDF export process that could potentially lead to arbitrary code execution.
CVE-2026-22904 2026-06-17 N/A 9.8 CRITICAL
Improper length handling when parsing multiple cookie fields (including TRACKID) allows an unauthenticated remote attacker to send oversized cookie values and trigger a stack buffer overflow, resulting in a denial‑of‑service condition and possible remote code execution.
CVE-2026-22903 2026-06-17 N/A 9.8 CRITICAL
An unauthenticated remote attacker can send a crafted HTTP request containing an overly long SESSIONID cookie. This can trigger a stack buffer overflow in the modified lighttpd server, causing it to crash and potentially enabling remote code execution due to missing stack protections.
CVE-2026-22790 1 Linuxfoundation 1 Everest 2026-06-17 N/A 8.8 HIGH
EVerest is an EV charging software stack. Prior to version 2026.02.0, `HomeplugMessage::setup_payload` trusts `len` after an `assert`; in release builds the check is removed, so oversized SLAC payloads are `memcpy`'d into a ~1497-byte stack buffer, corrupting the stack and enabling remote code execution from network-provided frames. Version 2026.02.0 contains a patch.
CVE-2026-22321 2026-06-17 N/A 5.3 MEDIUM
A stack-based buffer overflow in the device's Telnet/SSH CLI login routine occurs when a unauthenticated attacker send an oversized or unexpected username input. An overflow condition crashes the thread handling the login attempt, forcing the session to close. Because other CLI sessions remain unaffected, the impact is limited to a low‑severity availability disruption.
