FreeRDP versions before 3.31.0 contain an out-of-bounds write vulnerability in server-side static virtual channel handling when CHANNEL_OPTION_SHOW_PROTOCOL is enabled. Authenticated clients can queue oversized channel messages that cause buffer underflow and corrupt heap memory including live pointers, potentially enabling code execution.

Integer underflow (wrap or wraparound) in Skype for Business allows an unauthorized attacker to deny service over a network.

Integer underflow (wrap or wraparound) in Windows File History Service allows an authorized attacker to elevate privileges locally.

Integer underflow (wrap or wraparound) in Windows Remote Access Connection Manager allows an authorized attacker to execute code over a network.

Time-of-check time-of-use (toctou) race condition in Windows USB Audio Class driver (usbaudio.sys) allows an authorized attacker to elevate privileges locally.

Integer underflow (wrap or wraparound) in Windows USB Audio Class driver (usbaudio.sys) allows an authorized attacker to elevate privileges locally.

Integer underflow (wrap or wraparound) in Microsoft Standard XPS allows an authorized attacker to elevate privileges locally.

SAP NetWeaver Application Server for ABAP and ABAP Platform allows an unauthenticated user to send a specially crafted packet that triggers reprocessing of a previously buffered user request, potentially hijacking another user's session under narrow timing conditions. Successful exploitation could result in high impact on confidentiality and integrity, with low impact on availability of the application.

A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), the wrapped-record length read from the wire is validated only against an upper bound. A small wire length (0, 1, or 2) produces an encrypted_buffer_count below the already-consumed encrypted_buffer_offset, causing an unsigned subtraction underflow in sasl_io_read_packet(). PR_Recv is then requested to read approximately 4 GiB into a 1024-byte heap buffer, resulting in a heap buffer overflow with attacker-controlled content. After a successful SASL bind with integrity protection (SSF > 0), a remote authenticated attacker can cause a denial of service or potentially achieve remote code execution. This flaw is distinct from CVE-2026-11774, whose fix only guards against upper-bound overflow.

MOOS essential-moos through 10.0.1 contains a buffer overflow vulnerability in CMOOSUDPLink::ReadPktFromArray() that allows remote attackers to corrupt heap memory by sending UDP datagrams with negative declared lengths. Attackers can send crafted UDP packets to the configured UDPListen port to trigger an oversized memcpy operation that writes past the destination buffer, causing heap corruption and denial of service.

A denial-of-service security issue exists within RSLinx® Classic. A crafted CIP packet can cause the RSLinx® Classic service to crash due to insufficient data length validation, requiring a  restart of the service to recover.

A denial-of-service security issue exists within RSLinx® Classic. A crafted CIP packet targeting the Forward Close service can cause the RSLinx® Classic service to crash, requiring a restart of the service to recover.

An integer underflow vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.

An integer underflow vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.

Any remote client can crash a NSD serve child, by throttling the TCP receive window after a TCP query. By continuously crashing the serve childs, the remote client can denial all TCP service to this NSD instance.

CAI Content Credentials is affected by an Integer Underflow (Wrap or Wraparound) vulnerability that could result in an application denial-of-service. An attacker could exploit this vulnerability to crash the application, leading to a denial-of-service condition. Exploitation of this issue does not require user interaction.
