FreeBSD kernel Heap Buffer Overflow DoS

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...

CVE-2026-3038

The rtsock_msg_buffer() function in the FreeBSD kernel contains a stack buffer overflow vulnerability. The flaw occurs because the function fails to validate the source sockaddr length field before copying data into a sockaddr_storage structure on the stack. A malicious userspace program can craf...

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...
