libxml2: libxml2: Arbitrary code execution via heap-based buffer overflow

In libxml2 before 2.15.4, xmlDictAddQString in dict.c has an integer overflow and resultant heap-based buffer overflow.

The Continuous Glucose Monitoring Service's Record Access Control Point (RACP) write handler `memcpy`s the entire attacker-supplied ATT write value into a fixed 20-byte BSS buffer.

A buffer overflow in the Bluetooth Continuous Glucose Monitoring Service (CGMS) Record Access Control Point (RACP) write handler allows an authenticated BLE peer to overflow a 20-byte static buffer into adjacent BSS memory. The exploitable impact cannot be predetermined - it is entirely dependent on the linker-assigned BSS layout of the specific firmware build, which may vary.

A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). The length of the URL component contained in pre-authenticated HTTP messages is not properly validated before appending additional data to it, resulting in an out-of-bounds write condition in memory. This could allow an unauthenticated remote attacker to crash the affected device, causing a reboot and resulting in a denial-of-service condition.

Unitree G1 EDU 1.5.2 BLE GATT RCE via WiFi Provisioning Stack

Unitree G1 EDU firmware through 1.5.2 contains multiple chained vulnerabilities in the BLE GATT server and WiFi provisioning stack that allow unauthenticated proximate attackers to achieve root code execution without pairing or credentials by exploiting an unquoted heredoc variable in the WiFi provisioning script and a buffer overflow in the SSID chunk accumulator. Attackers can send crafted BLE writes to overflow a fixed BSS buffer across BLE connections, corrupting an adjacent mainloop function pointer dispatch entry that is subsequently invoked by the cleanup path passing attacker-controlled data to system() as uid 0.

OOBR and OOBW in libpcap before 1.10.7

In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading and writing the OS process memory in the 16GiB starting at the current stack frame on 64-bit architectures and in the entire address space on 32-bit architectures.

Out‑of‑Bounds Write in Android DRM Service Enables Local Privilege Escalation

In onTransact of IDrmManagerService.cpp, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Unidata netcdf-c through 4.10.1 Out-of-bounds Write via Oversized HDF5 Attribute Name

Unidata netcdf-c through 4.10.1 contains an out-of-bounds write vulnerability in NC4_HDF5_inq_attname() that copies HDF5 attribute names into a fixed 256-byte buffer without length validation. Attackers can craft HDF5 files with oversized attribute names to overflow the destination buffer, causing memory corruption and crashes when applications enumerate attribute names.

IBM i is Affected By Denial of Service Vulnerabilities in NFS [, ]

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service and compromise integrity due to a buffer overflow.

D-Link DIR-822A L2TP Control Message tunnel_set_params out-of-bounds write

A vulnerability has been found in D-Link DIR-822A A_101. Affected is the function tunnel_set_params of the component L2TP Control Message Parser. Such manipulation leads to out-of-bounds write. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.

Out-of-bounds write vulnerability in Samsung Opensource Walrus allows Overflow Buffers. This issue affects Walrus: af80e665ea49d9003695a66502f841ed1d8397e7.

Out-of-Bounds Write in Chrome WebGL Enables Remote Code Execution on Android

Out of bounds write in WebGL in Google Chrome on on Android prior to 152.0.7977.82 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)

Escargot: Escargot: Out-of-bounds write leads to Denial of Service

An out-of-bounds write caused by numeric truncation Samsung Open Source Escargot on Linux x86-64 allows an attacker who can supply JavaScript for execution to corrupt native memory and crash the host process via a crafted class definition whose instance initialization entry count exceeds UINT16_MAX. This issue affects Escargot: 5dc93606abd42b859045add05d704a038e197359.

openvpn: OpenVPN: Out-of-bounds write via crafted DOMAIN-SEARCH entries

OpenVPN 2.5.0 through 2.7.6 on Windows using the tap-windows6 driver allows attackers to trigger an out-of-bounds write via crafted DOMAIN-SEARCH entries

nokogiri: libxml2: Nokogiri: Integer overflow in libxml2 leads to information disclosure, data modification, or denial of service

This CVE ID has been rejected as a duplicate.

Out-of-Bounds Write Vulnerability in NI LabVIEW when loading VI

There is a memory corruption vulnerability recently discovered in NI LabVIEW that may result in information disclosure or arbitrary code execution.  Successful exploitation requires an attacker to get a user to open a specially crafted VI.  This vulnerability affects NI LabVIEW 2026 Q3 (26.3.0) and prior versions.

TeamDavid: Buffer Overflow in JSON-parsing

Tobit Laboratories AG TeamDavid's Webbox application implements an API endpoint that is vulnerable to a buffer overflow condition. By submitting a specially crafted JSON body, such as one that is at least 8 characters long and begins with a number, an unauthenticated attacker can cause the server to crash, resulting in denial of service. Depending on the stack state or if a stack canary can be disclosed through another vulnerability, this buffer overflow could potentially lead to remote code execution and full compromise of the server. This issue affects TeamDavid before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.

TeamDavid: Buffer Overflow in multiple form data parameters

Tobit Laboratories AG TeamDavid's Webbox application’s endpoint “//serverClient_close.html” is vulnerable to a buffer overflow vulnerability in multiple form data parameters. By submitting excessively long values in these parameters, an authenticated attacker can trigger a server crash, resulting in denial of service. Depending on the stack state or if a stack canary can be disclosed through another vulnerability, this buffer overflow could potentially be exploited for remote code execution, leading to full compromise of the server. This issue affects TeamDavid before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.

TeamDavid: Buffer Overflow in file names of file upload functionalities

Tobit Laboratories AG TeamDavid's Webbox application implements various file upload functionalities that are vulnerable to a buffer overflow condition. By specifying an excessively long filename in a file upload request, an unauthenticated attacker can trigger a crash of the server, resulting in a denial of service. Depending on the stack state or if a stack canary can be disclosed through another vulnerability, this buffer overflow could potentially be exploited for remote code execution, leading to full compromise of the server. This issue affects TeamDavid before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.

HID: hid-goodix-spi: validate report size to prevent stack buffer overflow

In the Linux kernel, the following vulnerability has been resolved: HID: hid-goodix-spi: validate report size to prevent stack buffer overflow goodix_hid_set_raw_report() builds a protocol frame in a 128-byte stack buffer (tmp_buf), writing an 11-12 byte header followed by the caller-supplied report data. The HID core caps report size at HID_MAX_BUFFER_SIZE (16384) by default, while the driver does not set hid_ll_driver.max_buffer_size and performs no bounds checking before copying the payload: memcpy(tmp_buf + tx_len, buf, len); A hidraw SET_REPORT ioctl with a report larger than ~116 bytes overflows the stack buffer. Add a size check after constructing the header, rejecting reports that would exceed the buffer capacity. Discovered by Atuin - Automated Vulnerability Discovery Engine.
