CWE-121 Oct 7, 2026
Cisco Nexus 3000 and 9000 Series Switches VXLAN OAM (NGOAM) Remote Code Execution Vulnerability
A vulnerability in the VXLAN Operation, Administration, and Maintenance (OAM) feature of Cisco NX-OS Software, known as NGOAM, could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a Denial-of-Service (DoS) on an affected device.
This vulnerability is due to improper input validation of IP traffic when the NGOAM feature is enabled. An attacker could exploit this vulnerability by sending crafted packets to an IP interface on an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes resulting in a reload and DoS condition.

CWE-121 Oct 7, 2026
Bluetooth Mesh solicitation PDU stack buffer overflow via oversized advertisement
The Bluetooth Mesh On-Demand Private Proxy solicitation handler in subsys/bluetooth/mesh/solicitation.c copies a received Solicitation PDU into a fixed 17-byte stack buffer without bounding the source length. In sol_pdu_decrypt(), out is allocated as NET_BUF_SIMPLE(17) and then filled with net_buf_simple_add_mem(out, in->data, in->len); net_buf_simple_add() guards its tailroom only with __ASSERT_NO_MSG, which is compiled out in production builds, so when in->len > 17 the underlying memcpy writes attacker-controlled bytes past the 17-byte stack buffer. The copy occurs before any decryption or authentication, so no key material is required to trigger it.
The oversized length arises because the mesh scan callback in subsys/bluetooth/mesh/adv.c calls net_buf_simple_restore() before dispatching to bt_mesh_sol_recv(), leaving buf->len covering the entire remaining advertising payload rather than just the Solicitation Service Data. After the parser locates the Service Data AD and consumes the Identification Type byte, the remaining buf->len is the 17-octet Network PDU plus any trailing advertising bytes, and prior to this fix there was no maximum-length check (only a minimum). An attacker can therefore append extra AD structures or padding after the Solicitation Service Data to make buf->len exceed 17.
bt_mesh_scan_cb() is registered directly as the BLE scan callback, so buf is raw, unauthenticated advertising data received over the air. Any device in radio range can send a non-connectable advertisement carrying a crafted mesh Proxy Solicitation to a node that has CONFIG_BT_MESH_OD_PRIV_PROXY_SRV enabled and is currently eligible to be solicited (GATT proxy disabled, On-Demand Private Proxy enabled), with no pairing, bonding, or provisioning. The result is an attacker-controlled stack overwrite — plausibly leading to remote code execution and at minimum a reliable remote denial of service. The fix trims buf->len to the spec-fixed 17 octets (dropping the PDU if fewer remain) before decryption.

wstrncat() unsigned integer underflow leads to an off-by-one null write in wolfSSH on non-Windows platforms
Unsigned integer underflow in wstrncat() in src/port.c in wolfSSL wolfSSH from v1.4.11 through v1.5.0 on non-Windows platforms allows an authenticated remote attacker to write one out-of-bounds null byte past the end of a stack buffer by sending a crafted SFTP path. wolfSSH_RealPath() in src/ssh.c appends each path component with a remaining-size bound (outSz - curSz) rather than the full destination size, so once the accumulated path reaches half the output buffer the size_t computation n - strlen(s1) - 1 wraps to near SIZE_MAX. The strncat() call is then effectively unbounded and copies the whole component; when that component exactly fills the remainder of the buffer, its terminating null is written one byte past the end. The caller's own length check keeps the copied data inside the buffer, so the overflow is limited to that single null byte, which may corrupt an adjacent stack value and crash the process. Applications that call the public wolfSSH_RealPath() with an output buffer smaller than the input path are additionally exposed to an unbounded copy, because the word32 expression outSz - segSz in that length check also wraps.

Authenticated ONVIF PTZ Out-of-Bounds Stack Write Denial of Service in TP-Link Tapo C500
TP-Link Tapo
C500 v2.0 contains an out-of-bounds stack write vulnerability in its ONVIF PTZ
SOAP handlers. An authenticated ONVIF client can submit an excessive number of
preset-related elements, causing writes beyond the bounds of fixed-size stack
arrays and resulting in a crash of the affected service.
Successful
exploitation may allow an authenticated attacker to cause the affected service
to crash, resulting in a denial-of-service condition. Repeated exploitation may
repeatedly disrupt camera management and PTZ-related functionality until the
service recovers or restarts.

Stack-based Buffer Overflow in Moxa MGate MB3170 Series
A stack-based buffer overflow vulnerability exists in protocol gateways' account management interface. The vulnerability is caused by insufficient length validation of the `account_name` parameter when processing account management requests. An attacker authenticated as a read-only user to the web management interface could supply a specially crafted account name that exceeds the size of the internal stack buffer, resulting in corruption of program execution flow. Successful exploitation could allow an attacker to read sensitive information from device memory, including credentials, modify arbitrary memory contents, and disrupt device availability.
