CVE-2026-18909 2026-08-06 4.7 Medium
A stack-based buffer overflow vulnerability exists in ELAN Microelectronics Corp. ELAN Smart-Pad on Windows (ETD.sys and ETDSMBus.sys). During Intel SMBus recovery, ETDSMBus.sys does not enforce an upper-bound check on the hardware-derived report count, allowing an out-of-range value to be forwarded to ETD.sys where it is used as a loop counter for a stack buffer copy without destination size validation. A local attacker with standard user privileges can trigger a kernel bugcheck (BSOD 0xF7 DRIVER_OVERRAN_STACK_BUFFER), resulting in denial of service. This issue affects ELAN Smart-Pad through ETD24.21.52.3.
CVE-2026-67673 2026-08-05 4.6 Medium
A stack-based buffer overflow vulnerability exists in the cmd_edl function of OreSat Firmware v1.0. The vulnerability is triggered when processing the edl fw_flash command, where the <filename> argument is copied to a 64-byte stack buffer via memcpy without proper length validation. An attacker with physical access to the UART3 serial interface can exploit this vulnerability by sending a maliciously crafted command with an oversized filename parameter,
CVE-2026-18898 1 Utt 1 Hiper 1200gw 2026-08-05 8.8 High
A security flaw has been discovered in UTT HiPER 1200GW up to v2.5.3-170306. This affects the function strcpy of the file /goform/ConfigAdvideo. The manipulation of the argument timestart results in stack-based buffer overflow. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-71267 1 Rxi 1 Microtar 2026-08-05 9.8 Critical
microtar's mtar_write_file_header() and mtar_write_dir_header() functions (src/microtar.c) copy a caller-supplied entry name into the 100-byte `name` field of a stack-allocated mtar_header_t via strcpy(h.name, name), with no check that strlen(name) is less than 100 before the copy. Any application that calls these functions with an externally-influenced filename longer than 99 characters (e.g. when archiving user-supplied or attacker-controlled filenames) triggers a stack buffer overflow.
CVE-2026-71266 2026-08-05 7.8 High
tinyobjloader-c's tinyobj_parse_and_index_mtl_file() (tinyobj_loader_c.h) reads each line of a .mtl material file into a fixed 4096-byte stack buffer `linebuf` via memcpy(linebuf, p, p_len), guarded only by `assert(p_len < 4095)`. Because assert() compiles to a no-op under -DNDEBUG (standard for release builds), a crafted .mtl file containing a line (e.g. a "newmtl" material name) longer than 4096 bytes overflows linebuf into the adjacent stack variable namebuf and beyond, corrupting the stack of any application that loads attacker-supplied 3D model/material files. The identical vulnerable pattern is duplicated in a second function in the same file.
CVE-2026-71265 1 Domoticz 1 Domoticz 2026-08-05 7.5 High
Domoticz's MochadTCP::MatchLine() handler for MOCHAD_RFSEC messages (hardware/MochadTCP.cpp) copies network-received data from the up-to-1028-byte m_mochadbuffer into a fixed 50-byte stack buffer tempRFSECbuf using strcpy() with no length check, across three separate code branches (DS10A/KR10A/MS10A device types). An attacker on the local network segment able to reach the Mochad TCP bridge (default port 1099, no authentication) can send a crafted packet that overflows tempRFSECbuf by up to several hundred bytes, corrupting the Domoticz worker thread's stack.
CVE-2026-18897 1 Utt 1 Hiper 1250gw 2026-08-05 8.8 High
A vulnerability was identified in UTT HiPER 1250GW up to v3.2.7-210907-180535. The impacted element is the function strcpy of the file /goform/getOneApConfTempEntry. The manipulation of the argument tempName leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-45538 1 Opensips 1 Opensips 2026-08-05 9.8 Critical
OpenSIPS is a Session Initiation Protocol (SIP) server implementation. In versions 4.0.0 and prior, processing a SIP message with a header name longer than 255 bytes causes a stack buffer overflow when sip_to_json() is called in the routing script. Function sip_to_json() (modules/sipmsgops/sipmsgops.c) copies SIP header names into a fixed 255-byte stack buffer without bounds checking, performing a memcpy of the full header-name length even though the SIP parser imposes no such limit (a header name can be roughly 65000 bytes). As a result, when a routing script calls sip_to_json(), a SIP message with a header name longer than 255 bytes triggers a stack buffer overflow in which both the length and content of the overwrite are attacker-controlled, corrupting the saved frame pointer and return address. A single unauthenticated UDP packet to the SIP port (5060) can crash the process or, on builds without stack protections, hijack the return address to achieve remote code execution. This affects deployments whose routing script invokes sip_to_json(). This issue was not fixed at the time of publication.
CVE-2026-18895 1 Utt 1 Hiper 1250gw 2026-08-05 8.8 High
A vulnerability was found in UTT HiPER 1250GW up to 3.2.7-210907-180535. Impacted is the function strcpy of the file /goform/APSecurity_5g. Performing a manipulation of the argument cipher results in stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-61486 1 Apache 1 Lucy 2026-08-05 9.8 Critical
** UNSUPPORTED WHEN ASSIGNED ** Stack-based Buffer Overflow vulnerability in Apache Lucy. This issue affects Apache Lucy: all versions. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
CVE-2026-45809 1 Opensips 1 Opensips 2026-08-05 N/A
OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Versions prior to 3.6.6 and 4.0.0-rc1 contain a denial of service vulnerability in the watcherinfo generation functionality. An attacker can create an oversized watcher entry by sending a SUBSCRIBE Event: presence request with a long From URI, and then trigger presence.winfo watcherinfo XML generation for the same presentity. OpenSIPS copies the stored watcher URI into a fixed-size stack buffer, overflowing it and crashing the process. A remote attacker can crash an OpenSIPS worker in deployments that expose handle_subscribe() and allow watcherinfo (presence.winfo) generation. The issue is configuration-dependent because the presence and presence_xml modules must be loaded and SUBSCRIBE routing must be reachable. This issue has been fixed in versions 3.6.6 and 4.0.0-rc1.

CVE-2025-5278 1 Redhat 7 Cost Management, Discovery, Enterprise Linux and 4 more 2026-08-05 4.4 Medium
A flaw was found in GNU Coreutils. The sort utility's begfield() function is vulnerable to a heap buffer under-read. The program may access memory outside the allocated buffer if a user runs a crafted command using the traditional key format. A malicious input could lead to a crash or leak sensitive data.
CVE-2026-9669 1 Python 1 Cpython 2026-08-05 5.9 Medium
bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash the process when processing untrusted data.
