A stack-based buffer overflow vulnerability was found in the File Explorer on the ADM
A stack-based buffer overflow vulnerability was found in the File Explorer on the ADM. The vulnerability occurs because user-controlled input is not properly validated before being decoded and copied into a fixed-size stack buffer. An authenticated attacker can exploit this issue to cause denial of service of the affected CGI process. Further impact may be possible depending on exploitability and runtime protections.
Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81.

Autel MaxiCharger AC Elite Home NFC Stack-based Buffer Overflow Arbitrary Code Execution Vulnerability
Autel MaxiCharger AC Elite Home NFC Stack-based Buffer Overflow Arbitrary Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Elite Home EV chargers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of card responses via the NFC interface. A crafted card response can trigger an overflow of a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-29044.

GStreamer qtdemux Stack-based Buffer Overflow Remote Code Execution Vulnerability
GStreamer qtdemux Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the parsing of UncompressedFrameConfigBox structures. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29392.

CWE-121 29/07/2026
Unauthenticated Remote Code Execution in TP-Link TL-WR940N RTSP Conntrack Feature
The
TL-WR940N v6 router contains a vulnerability in its RTSP connection tracking
module that can lead to a stack-based buffer overflow. The issue occurs when a
LAN client initiates a connection to a malicious RTSP server controlled by an
attacker. A specially crafted RTSP message may trigger improper memory handling
within the kernel module
Successful
exploitation of this vulnerability may result in a denial-of-service (DoS)
condition or allow remote code execution (RCE), potentially leading to full
compromise of the device. This vulnerability can be exploited by an
unauthenticated attacker under the device's default configuration.

Xlight FTP Server < 3.9.5 Pre-Auth Stack Buffer Overflow via SSH GCM Cipher
Xlight FTP Server before 3.9.5 contains a pre-authentication stack buffer overflow vulnerability that allows unauthenticated attackers to corrupt stack memory by sending malformed SSH packets when a GCM cipher is negotiated. Attackers can craft packets with an unvalidated length field passed directly to the GCM decrypt function, overwriting the stack cookie and return address to potentially achieve remote code execution before any authentication occurs.

CWE-121 27/07/2026
Bluetooth: eir: Fix stack OOB write when prepending the Flags AD
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: eir: Fix stack OOB write when prepending the Flags AD
eir_create_adv_data() builds the advertising data into a fixed-size
buffer ("size", 31 for the legacy path). It may prepend a 3-byte "Flags"
AD structure (LE_AD_NO_BREDR on an LE-only controller) and then copies
the per-instance data without checking that it still fits:
memcpy(ptr, adv->adv_data, adv->adv_data_len);
tlv_data_max_len() only reserves those 3 bytes when the user-supplied
flags carry a managed-flags bit, so an instance added with flags == 0 is
accepted with adv_data_len up to the full buffer. At advertise time the
flags are still prepended, and the memcpy() writes 3 + adv_data_len
bytes into the size-byte buffer:
BUG: KASAN: stack-out-of-bounds in eir_create_adv_data (net/bluetooth/eir.c:301)
Write of size 31 at addr ffff88800a547bdc by task kworker/u9:0/65

hci_cmd_sync_work (net/bluetooth/hci_sync.c:332)
This frame has 1 object:
[32, 64) 'cp'
The "Flags" structure is added by the kernel, not requested by
userspace, so only prepend it when it fits together with the instance
advertising data; when there is no room for both, drop the flags rather
than the user-provided data.
Reachable by a local user with CAP_NET_ADMIN owning an LE-only
controller on the legacy advertising path.

Multiple Security Vulnerabilities in Snowflake libsnowflakeclient
Multiple security vulnerabilities in Snowflake libsnowflakeclient versions prior to 2.9.2 could allow remote code execution and credential exfiltration. A stack-based buffer overflow in the file download path could allow remote code execution on a victim host. An attacker could exploit this by uploading a file with a crafted encryption metadata field to a shared internal stage that a victim process later downloads, and impact would be limited to deployments where principals with different privilege levels share the same internal stage. A related out-of-bounds write in the same download path could allow memory corruption with attacker-controlled write primitives. An attacker may exploit this through a crafted initialization vector metadata field on a shared stage, and impact would be limited by the same stage-write precondition. Improper validation of connection parameters could allow an attacker-controlled input to redirect outbound authentication requests — including credentials and tokens — to an attacker-controlled endpoint. Impact is limited to embedding deployments where a lower-privileged principal can influence connection configuration while higher-privileged service credentials are in use. The fix is available in Snowflake libsnowflakeclient version 2.9.2. The Snowflake PHP PDO Driver and Snowflake ODBC Driver embed the affected library; fixes are available in versions 4.1.0 and 3.19.0 respectively. Users must manually upgrade.

FFmpeg 8.0 - 8.1.2 Stack Buffer Overflow in Vulkan HEVC Decoder
FFmpeg versions 8.0 through 8.1.2 contains a stack buffer overflow vulnerability in the Vulkan HEVC hardware decoder that allows remote attackers to overwrite return addresses and adjacent stack frames by supplying a crafted HEVC/H.265 bitstream. Attackers can embed a malicious vps_num_hrd_parameters value exceeding HEVC_MAX_SUB_LAYERS in any supported container format to overflow stack-allocated arrays in the vk_hevc_end_frame function, potentially achieving arbitrary code execution.

Data::RingBuffer::Shared versions before 0.04 for Perl allow a stack buffer overflow via an unvalidated elem_size in ring_read_seq
Data::RingBuffer::Shared versions before 0.04 for Perl allow a stack buffer overflow via an unvalidated elem_size in ring_read_seq.
The attach-time validator ring_validate_header checks the capacity-overflow and total_size consistency of the header but never caps elem_size against the destination size. ring_read_seq does memcpy(out, ring_slot(h, seq), elem_size) with elem_size read raw from the mmap'd segment, copying into a fixed 8-byte destination scalar. An elem_size larger than 8 bytes writes past the destination.
A local peer that can write the backing file can leave the header valid while setting a large elem_size, so the next read copies a file-controlled length into the fixed 8-byte stack buffer, corrupting adjacent stack frames.

Rpcbind: rpcbind: stack buffer overflow in rpcinfo rpcbdump() short-mode version-list formatting
A stack-based buffer overflow was found in rpcbind's rpcinfo utility. In rpcbdump() short mode (used by `rpcinfo -s`), version numbers from a remote RPCBPROC_DUMP reply are written into a fixed-size stack buffer without bounds checking. A user or administrator who runs `rpcinfo -s` against a malicious or compromised rpcbind endpoint could experience a crash or denial of service of the rpcinfo client.

Libssh: libssh: stack buffer overflow in sftp server longname construction
A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-controlled filenames, sufficiently long names can overflow that stack buffer and may lead to crashes or possible code execution on the server.
