CVE-2026-21068 1 Samsung Mobile 1 Samsung Mobile Devices 2026-08-11 N/A
Stack-based buffer overflow in libril_sem.so prior to SMR Aug-2026 Release 1 allows privileged local attackers to execute arbitrary code.
CVE-2026-9669 1 Python 1 Cpython 2026-08-11 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.

CVE-2026-19341 1 Utt 1 Hiper 1200gw 2026-08-10 8.8 High
A security vulnerability has been detected in UTT HiPER 1200GW up to 2.5.3-170306. This impacts the function strcpy of the file /goform/pptpSrvGlobalConfig. Such manipulation of the argument EncryptionMode leads to stack-based buffer overflow. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-71267 1 Rxi 1 Microtar 2026-08-10 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 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.
CVE-2026-71266 1 Syoyo 1 Tinyobjloader-c 2026-08-10 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 via memcpy(linebuf, p, p_len), guarded only by . The identical vulnerable pattern is duplicated in a second function in the same file.
CVE-2026-71265 1 Domoticz 1 Domoticz 2026-08-10 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).
CVE-2026-55738 1 Rxi 1 Microtar 2026-08-10 8.8 High
A stack-based buffer overflow exists in the raw_to_header function in src/microtar.c in rxi microtar 0.1.0. The function copies the 100-byte name and linkname fields of a TAR header with strcpy without guaranteeing null termination of the source.
CVE-2026-20345 1 Cisco 1 Secure Endpoint 2026-08-08 7.5 High
A vulnerability in the GPT file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition or possibly other expanded impacts as a result of memory corruption on an affected device. This vulnerability is due to improper handling of an endian conversion operation, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerability by submitting a crafted GPT file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
CVE-2026-55141 1 Microsoft 17 365 Apps, Excel, Excel 2016 and 14 more 2026-08-07 7.8 High
Stack-based buffer overflow in Microsoft Office Excel allows an unauthorized attacker to execute code locally.
CVE-2026-55055 1 Microsoft 21 365 Apps, Microsoft 365, Microsoft 365 Apps For Enterprise and 18 more 2026-08-07 7.8 High
Stack-based buffer overflow in Microsoft Office Word allows an unauthorized attacker to execute code locally.
CVE-2026-57091 1 Microsoft 19 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 16 more 2026-08-07 7.8 High
Stack-based buffer overflow in Windows File History Service allows an authorized attacker to elevate privileges locally.
CVE-2026-18909 1 Elan Microelectronics Corp. 1 Elan Smart-pad 2026-08-07 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-2020-37121 1 Codeblocks 2 Code::blocks, Code\\ 2026-08-06 5.5 Medium
CODE::BLOCKS 16.01 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting Structured Exception Handler with crafted Unicode characters. Attackers can create a malicious text file with 1982 bytes of buffer and shellcode to trigger remote code execution.
CVE-2026-67866 1 Systerel 1 S2opc 2026-08-06 7.5 High
Buffer Overflow vulnerability in Systerel S2OPC 1.7.3 allows a remote attacker to cause a denial of service via the LockedStaMac_ProcessMsg_DeleteMonitoredItemsResponse and SOPC_StaMac_NewDeleteMonitoredItems in the client wrapper DeleteMonitoredItems path
CVE-2026-55980 1 Secureage 1 Catchpulse 2026-08-06 5.5 Medium
A denial-of-service vulnerability in CatchPulse could allow an attacker to conduct a stack buffer overrun attack, leading to a denial-of-service condition.
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.
