Zephyr 安全漏洞
Zephyr is an open-source, scalable real-time operating system RTOS developed by Zephyr. There is a security vulnerability in Zephyr, which stems from the use of NETASSERT for verifying buffer length only in the zcansendtoctx function. Disabling this feature in production builds may lead to...
CVE-2026-5072
A bitwise shift vulnerability in Zephyr's PTP subsystem allows a remote attacker to cause undefined behavior and potential system crashes. An attacker sends a crafted PTPMSGMANAGEMENT message to set an unvalidated negative logannounceinterval value in the port's data set. When a subsequent...

CVE-2026-5072
CVE-2026-5072 affects Zephyr’s PTP subsystem. A remote attacker can send a crafted PTP_MSG_MANAGEMENT to set an unvalidated negative log_announce_interval in a port’s data set. When a subsequent PTP_MSG_ANNOUNCE is processed, port_timer_set_timeout_random computes timeout as NSEC_PER_SEC >>...
Zephyr 安全漏洞
Zephyr is an open-source, scalable real-time operating system RTOS developed by Zephyr. There is a security vulnerability in Zephyr, caused by a bit offset issue. A remote attacker can set an unvalidated negative value of logannounceinterval by sending a specially crafted PTPMSGMANAGEMENT message...

A bitwise shift vulnerability in Zephyr's PTP subsystem allows a remote attacker to cause undefined behavior and potential system crashes. An attacker sends a crafted PTP MSG MANAGEMENT message to set an unvalidated negative log announce interval value in the port's data set. When a subsequent PT...
Zephyr 安全漏洞
Zephyr is an open-source, scalable real-time operating system RTOS developed by Zephyr. There is a security vulnerability in Zephyr, which occurs when sending ICMP ping messages to the device’s own IPv4 address using the net ping shell command. This causes the network stack to recursively re-ente...
CVE-2026-1677
Zephyr sockets created with IPPROTOTLS13 can still negotiate a TLS 1.2 connection when both TLS versions are enabled in Kconfig, because the socket-level protocol selection is not propagated to mbedTLS e.g. via mbedtlssslconfmintlsversion. The ClientHello advertises both versions and the peer can...
CVE-2026-1677
CVE-2026-1677 concerns Zephyr: sockets created with IPPROTO_TLS_1_3 may still negotiate TLS 1.2 when both TLS versions are enabled, because socket‑level protocol selection isn’t propagated to mbedTLS (e.g., via mbedtls_ssl_conf_min_tls_version). The ClientHello can advertise both TLS 1.2 and TLS ...
CVE-2026-1677 net: TLS 1.2 connections allowed on TLS 1.3 sockets
Zephyr sockets created with IPPROTOTLS13 can still negotiate a TLS 1.2 connection when both TLS versions are enabled in Kconfig, because the socket-level protocol selection is not propagated to mbedTLS e.g. via mbedtlssslconfmintlsversion. The ClientHello advertises both versions and the peer can...

Zephyr 安全漏洞
Zephyr is an open-source, scalable real-time operating system RTOS developed by Zephyr. There is a security vulnerability in Zephyr, which stems from race conditions during the termination of TCP connections. This vulnerability may lead to null pointer dereferencing and system crashes...
Zephyr 安全漏洞
Zephyr is an open-source, scalable real-time operating system RTOS developed by Zephyr. There is a security vulnerability in Zephyr, which stems from the socket driver’s behavior of copying user-provided payloads into fixed buffers without checking the available space. This could lead to kernel...
CVE-2026-0849
Malformed ATAES132A responses with an oversized length field overflow a 52-byte stack buffer in the Zephyr crypto driver, allowing a compromised device or bus attacker to corrupt kernel memory and potentially hijack execution...
Zephyr Buffer Overflow Vulnerability
Zephyr is Zephyr open source a scalable real-time operating system RTOS. Zephyr suffers from a buffer overflow vulnerability. The vulnerability stems from ATAES132A response parsing that fails to properly validate the length size of input data, which can be exploited by an attacker to cause kerne...
