Descripción técnica

PLANET GS-5220-8P2T2S (hardware version 3.0) firmware versions before 3.2412b261008 contains a stack-based buffer overflow vulnerability that allows unauthenticated attackers to corrupt stack memory by submitting an oversized webstax_auth HTTP Cookie value that is copied into a fixed-size stack buffer without length validation. Attackers can send a crafted unauthenticated HTTP request with an oversized cookie to overwrite the saved return address and corrupt stack memory, leading to memory corruption and potential denial of service on the device.

—

———IBM i 7.3 7.4, 7.5, and 7.6 is vulnerable to a stack buffer overflow, caused by improper bounds checking in the QFileSvr.400 file system. By sending a command in the QFileSvr.400 file system, a local authenticated attacker could cause undefined behavior.3h CVE-2026-1288855.5 MED

—

———A flaw was found in D-Bus. In configurations where the daemon falls back to using the Unix select() mechanism for event monitoring, it does not verify whether file descriptor numbers exceed allocated limits. A local attacker can exploit this flaw by opening a large number of concurrent connections to trigger an out-of-bounds write on the stack. This can cause the daemon to crash, resulting in a Denial of Service (DoS).3h CVE-2026-109093—

———A stack buffer overflow in ProcXTestFakeInput DeviceValuator handling in X.Org xwayland before 24.1.15 and X server before 21.1.26 could be used by authenticated clients to crash or execute code in the X server.10h CVE-2026-754935.9 MED

——0Cudy TR3000 before 2.5.42 contains a stack buffer overflow vulnerability in an obuspa getter for the TR-098 WLANConfiguration KeyPassphrase parameter, which copies the stored value with strcpy() into a 4,096-byte stack buffer without a length check. A malicious or compromised ACS can set a 5,000-byte passphrase via SetParameterValues, and a later read of the parameter overflows the buffer and crashes obuspa, causing denial of service.9h CVE-2026-754927.5 ALT

——0Cudy TR3000 before 2.5.42 contains an unauthenticated stack buffer overflow vulnerability in the stun_client TR-111 UDP Connection Request parser that parses requests before verifying username or HMAC. Remote attackers can send a single crafted UDP datagram lacking a space in the request line, causing strncpy() to overflow a 10-byte stack buffer and crash stun_client for denial of service.15h CVE-2026-754885.9 MED

——0Cudy TR3000 before 2.5.42 contains a stack buffer overflow vulnerability in the CWMP client that allows a malicious ACS to corrupt stack memory via oversized credentials. Attackers controlling the ACS can send Username and Password values up to 256 bytes in TR-069 Download or Upload requests, overflowing 128-byte stack buffers and crashing the CWMP process.15h
