The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-20345 2026-10-23 N/A 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-2026-115863 2026-10-23 N/A 7.6 HIGH
ConnMan through 2.0 has a stack-based buffer overflow via a DHCPv6 Reply message. This occurs in get_domains in gdhcp/client.c. It copies a fixed NS_MAXDNAME (1025) bytes from a DHCPv6 DOMAIN_LIST (option 24) value into a 1026-byte stack buffer dns_name regardless of the actual option length, then walks DNS labels with an unbounded "c += jump + 1" loop. A crafted DHCPv6 REPLY with a DOMAIN_LIST option of >= 1025 non-zero bytes makes the label walk leave the buffer and read/write '.' past its end in attacker-chosen strides. An on-link attacker can trigger this without authentication via a forged Router Advertisement (O=1) and a forged DHCPv6 REPLY matching xid/CLIENTID with a long DOMAIN_LIST. The impact is unauthenticated on-link crash of connmand (runs as root). This was introduced in bb06c47.
CVE-2026-19003 1 Mongodb 1 Bi Connector Odbc Driver 2026-10-23 N/A 7.8 HIGH
A data source definition containing an over-length file path setting may cause the MongoDB BI Connector ODBC Driver setup dialog to write outside the bounds of an allocated buffer. The issue stems from an incorrect buffer capacity calculation in the dialog's file and folder selection handling, and is reached only when a user opens the setup dialog for such a data source and initiates a file or folder selection. Depending on build configuration, the result may range from abnormal process termination to, under certain conditions, execution of unintended code in the context of the user running the dialog.
CVE-2026-40130 2026-10-23 N/A 5.3 MEDIUM
SAP SAPSPrint Service has memory corruption vulnerabilities in the handling of certain commands. An unauthenticated attacker could send specially crafted requests that trigger a buffer overflow in the affected component. This causes a temporary service interruption and automatic restart, resulting in low impact on availability but no impact on confidentiality and integrity.
CVE-2026-19695 1 Wireshark 1 Wireshark 2026-10-23 N/A 4.7 MEDIUM
Gammu DCT3 trace file parser crash in 4.6.0 to 4.6.7 allows denial of service
CVE-2026-11733 1 Netgear 22 Rax41, Rax41 Firmware, Rax41v2 and 19 more 2026-10-23 N/A 4.9 MEDIUM
A buffer overflow vulnerability in the listed NETGEAR models allows a device administrator to temporarily interrupt the normal operation of the affected device.
CVE-2026-10534 1 Ibm 1 Db2 2026-10-23 N/A 8.4 HIGH
IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.5 is vulnerable to buffer overflow in the IXF IMPORT parser.
CVE-2026-13361 1 Ibm 1 Informix Dynamic Server 2026-10-23 N/A 8.8 HIGH
IBM Informix oninit sq_sgkprepare RCE via unchecked SQL Interface length field.
CVE-2026-11734 1 Netgear 30 Mr70, Mr70 Firmware, Mr90 and 27 more 2026-10-23 N/A 2.7 LOW
A buffer overflow vulnerability in the listed NETGEAR models allows an authenticated admin user to cause the affected device to become temporarily unavailable.
CVE-2026-12665 1 Ibm 2 Mq Operator, Supplied Mq Advanced Container Images 2026-10-23 N/A 8.1 HIGH
IBM MQ could allow a remote attacker to execute arbitrary code due to a stack buffer overflow when processing TLS certificates with malformed distinguished names during channel connection establishment.
CVE-2026-73522 2026-10-23 N/A 7.5 HIGH
COVESA Open1722 through 0.9.2 contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to write past the end of a fixed 15-slot stack array by sending a crafted UDP datagram containing more than 15 ACF-CAN messages. The avtp_to_can() function increments its write index without bounding it against the caller-supplied array size, and because the listener accepts datagrams from any sender matching a hardcoded unauthenticated stream ID transmitted in plaintext, attackers can corrupt adjacent stack memory to achieve arbitrary code execution or denial of service.
CVE-2026-71979 2026-10-23 N/A 7.5 HIGH
INDI (Instrument Neutral Distributed Interface) indiserver through 2.2.4.2, fixed in commit 96bbd7f, contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to crash the daemon by sending malformed XML with mismatched tags whose names exceed 1024 bytes. Attackers can send a single TCP packet on port 7624 with mismatched XML tags to trigger an unbounded sprintf() write into a fixed 1024-byte stack buffer in MsgQueue.cpp, terminating the daemon and disrupting all active client and driver sessions.
CVE-2026-67967 2026-10-23 N/A 9.8 CRITICAL
Buffer Overflow vulnerability in Tenda W20E V16.01.0.6(2782) allows an attacker to execute arbitrary code. This is an incomplete fix for CVE-2025-44867 and CVE-2026-36819
CVE-2026-92183 2026-10-23 N/A 7.8 HIGH
GIMP APNG File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of APNG files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29400.
CVE-2026-76587 2026-10-23 N/A 8.8 HIGH
IBM Planning Analytics 2.0 and 2.1 are vulnerable to a stack-based buffer overflow, caused by improper bounds checking. An attacker could overflow the buffer and execute arbitrary code on the system.
