CVE-2026-68768 2026-10-14 N/A 6.1 MEDIUM
hashcat contains a heap-based buffer overflow (out-of-bounds write) in the outfile_write() function in src/outfile.c. When assembling output into a fixed-size buffer (HCBUFSIZ_LARGE, ~16 MB), the function sequentially appends the username, separator, hash, and plaintext via memcpy without validating that the accumulated length stays within the buffer capacity. When run with --username --show against a crafted hash file containing an oversized username that nearly fills the buffer, the total assembled output exceeds the buffer, causing a heap buffer overflow that can corrupt memory and crash the process.
CVE-2025-59947 1 Emqx 1 Nanomq 2026-10-14 N/A 9.0 CRITICAL
NanoMQ is a messaging broker/bus for IoT Edge & SDV. Versions prior to 0.24.4 have a buffer overflow case while the PUBLISH packets trigger both shared subscription and vanila subscription. This is fixed in version 0.24.4. As a workaround, disable shared subscription.
CVE-2021-3177 5 Debian, Fedoraproject, Netapp and 2 more 10 Debian Linux, Fedora, Active Iq Unified Manager and 7 more 2026-10-14 7.5 HIGH 9.8 CRITICAL
Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to remote code execution in certain Python applications that accept floating-point numbers as untrusted input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used unsafely.
CVE-2020-12723 5 Fedoraproject, Netapp, Opensuse and 2 more 16 Fedora, Oncommand Workflow Automation, Snap Creator Framework and 13 more 2026-10-14 5.0 MEDIUM 7.5 HIGH
regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.
CVE-2026-53420 2026-10-14 N/A 8.0 HIGH
Buffer overflow in a Zoom Phone feature of Zoom Workplace Clients may allow an unauthenticated user to conduct a escalation of privilege via network access.
CVE-2025-9558 2026-10-13 N/A 7.6 HIGH
There is a potential OOB Write vulnerability in the gen_prov_start function in pb_adv.c. The full length of the received data is copied into the link.rx.buf receiver buffer without any validation on the data size.
CVE-2025-9557 2026-10-13 N/A 7.6 HIGH
‭An out-of-bound write can lead to an arbitrary code execution. Even on devices with some form of memory protection, this can still lead to‬ ‭a crash and a resultant denial of service.‬
CVE-2026-108915 2026-10-13 9.0 HIGH 9.9 CRITICAL
A vulnerability has been found in Edimax BR-6208AC 1.32. This affects an unknown part of the file /goform/formWlanMP. Such manipulation of the argument ateBW leads to buffer overflow. The attack can be executed remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.
CVE-2025-65834 1 Meltytech 1 Shotcut 2026-10-13 N/A 9.8 CRITICAL
Meltytech Shotcut 25.10.31 is vulnerable to Buffer Overflow. A memory access violation occurs when processing MLT project files with manipulated width and height parameters. By setting these values to extremely large numbers, the application attempts to allocate excessive memory during image processing, triggering a buffer overflow in the mlt_image_fill_white function.
CVE-2025-50681 1 Pali 1 Igmpproxy 2026-10-13 N/A 7.5 HIGH
igmpproxy 0.4 before commit 2b30c36 allows remote attackers to cause a denial of service (application crash) via a crafted IGMPv3 membership report packet with a malicious source address. Due to insufficient validation in the `recv_igmp()` function in src/igmpproxy.c, an invalid group record type can trigger a NULL pointer dereference when logging the address using `inet_fmtsrc()`. This vulnerability can be exploited by sending malformed multicast traffic to a host running igmpproxy, leading to a crash. igmpproxy is used in various embedded networking environments and consumer-grade IoT devices (such as home routers and media gateways) to handle multicast traffic for IPTV and other streaming services. Affected devices that rely on unpatched versions of igmpproxy may be vulnerable to remote denial-of-service attacks across a LAN .
CVE-2025-67073 1 Tenda 2 Ac10, Ac10 Firmware 2026-10-13 N/A 9.8 CRITICAL
A Buffer overflow vulnerability in function fromAdvSetMacMtuWan of bin httpd in Tenda AC10V4.0 V16.03.10.20 allows remote attackers to cause denial of service and possibly code execution by sending a post request with a crafted payload (field `serviceName`) to /goform/AdvSetMacMtuWan.
CVE-2025-50398 1 Mercurycom 2 D196g, D196g Firmware 2026-10-13 N/A 9.8 CRITICAL
Mercury D196G d196gv1-cn-up_2020-01-09_11.21.44 is vulnerable to Buffer Overflow in the function sub_404CAEDC via the parameter fac_password.
CVE-2025-50401 1 Mercurycom 2 D196g, D196g Firmware 2026-10-13 N/A 9.8 CRITICAL
Mercury D196G d196gv1-cn-up_2020-01-09_11.21.44 is vulnerable to Buffer Overflow in the function sub_404CAEDC via the parameter password.
CVE-2025-67074 1 Tenda 2 Ac10, Ac10 Firmware 2026-10-13 N/A 6.5 MEDIUM
A Buffer overflow vulnerability in function fromAdvSetMacMtuWan of bin httpd in Tenda AC10V4.0 V16.03.10.20 allows remote attackers to cause denial of service and possibly code execution by sending a post request with a crafted payload (field `serverName`) to /goform/AdvSetMacMtuWan.
CVE-2025-68114 1 Capstone-engine 1 Capstone 2026-10-13 N/A 4.8 MEDIUM
Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStream_concat lets a malicious cs_opt_mem.vsnprintf drive SStream’s index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Commit 2c7797182a1618be12017d7d41e0b6581d5d529e fixes the issue.
CVE-2025-66647 1 Riot-os 1 Riot 2026-10-13 N/A 9.8 CRITICAL
RIOT is an open-source microcontroller operating system, designed to match the requirements of Internet of Things (IoT) devices and other embedded devices. A vulnerability was discovered in the IPv6 fragmentation reassembly implementation of RIOT OS v2025.07. When copying the contents of the first fragment (offset=0) into the reassembly buffer, no size check is performed. It is possible to force the creation of a small reassembly buffer by first sending a shorter fragment (also with offset=0). Overflowing the reassembly buffer corrupts the state of other packet buffers which an attacker might be able to used to achieve further memory corruption (potentially resulting in remote code execution). To trigger the vulnerability, the `gnrc_ipv6_ext_frag` module must be included and the attacker must be able to send arbitrary IPv6 packets to the victim. Version 2025.10 fixes the issue.
CVE-2025-40815 2026-10-13 N/A 7.2 HIGH
