The vulnerability of the rtsock_msg_buffer() function in the operating system kernel of FreeBSD, which allows a hacker to cause a service failure

The vulnerability of the rtsockmsgbuffer function in the kernel of the FreeBSD operating system is related to writing beyond the buffer’s memory boundaries. Exploiting this vulnerability can allow a remote attacker to cause a service failure...

CVE-2026-3038 Local DoS and possible privilege escalation via routing sockets

The rtsockmsgbuffer function serializes routing information into a buffer. As a part of this, it copies sockaddr structures into a sockaddrstorage structure on the stack. It assumes that the source sockaddr length field had already been validated, but this is not necessarily the case, and it's...

FreeBSD 安全漏洞

FreeBSD is a Unix-like operating system developed by the FreeBSD Foundation. FreeBSD has a security vulnerability that stems from the rtsockmsgbuffer function not verifying the length field of the source sockaddr. This can lead to a stack buffer overflow, potentially causing a kernel crash...
