CVE-2026-68742 Sssd: sssd: nss responder out-of-bounds read via unchecked addrlen in gethostbyaddr

A flaw was found in SSSD. The sssnssprotocolparseaddr function in the NSS responder does not validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a crafted GETHOSTBYADDR request to the NSS responder socket, causing an out-of-bounds read and...

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 fact that the tlssessionstore and tlssessionrestore functions in the TLS socket connection path do not validate the addrlen value. This leads t...
