FreeBSD
A mature open-source Unix-like operating system with a fully open kernel codebase. It is widely used in servers, embedded systems, and the underlying layers of gaming consoles, and is known for its stability and security.
Core Facts
Timeline (last 90 days)
FreeBSD, NetBSD and OpenBSD, systems directly descended from UNIX lineage, are not certified as UNIX by the Open Group.
XNU's BSD subsystem derives directly from FreeBSD, providing POSIX system calls, the process model and the network stack.
Linux compatibility layers (such as FreeBSD's linuxulator and NetBSD's Linux emulation) implement the Linux system call interface in the native kernel so that Linux binaries can run without modification.
OpenBSD's bar for admitting new ports is higher than that of FreeBSD's ports collection and pkgsrc.
By bypassing authentication and triggering an unhandled termination of NSPPE, attackers established initial root-level access on the underlying FreeBSD platform.
NSPPE is the underlying core component of NetScaler that handles network traffic, runs on the FreeBSD platform, and operates as a high-privilege (usually root-level) process.
The PS5 uses a custom AMD Zen 2 CPU and RDNA 2 GPU, its system software is based on a FreeBSD derivative, and it uses a custom system called Orbis OS.
NetBSD, unlike FreeBSD, does not have a large number of commercial deployments in the server market, nor is it known for security auditing like OpenBSD.
The underlying system of the PS5 is based on FreeBSD.
FreeBSD is an open-source Unix-like operating system whose kernel code is fully public.

50%Unverifiedkqueue originated in FreeBSD and works through two system calls, kqueue and kevent, with kevent handling both registration and event retrieval
50%UnverifiedThe signal SIGBUS is numbered 7 on Linux and 10 on FreeBSD.
50%UnverifiedBoth Linux and FreeBSD use ELF as their executable file format, but the true compatibility barrier lies in differences in the system call interface (syscall ABI).
50%UnverifiedThe EI_OSABI field in the ELF header is used to identify the target operating system; FreeBSD sets it to ELFOSABI_FREEBSD (value 9), while Linux typically uses ELFOSABI_NONE or ELFOSABI_LINUX.
50%UnverifiedBSDun is an open-source project whose goal is to add native support for FreeBSD ELF binaries to the Linux kernel, allowing FreeBSD programs to run on the Linux kernel without recompilation.
50%UnverifiedThe system call number for the open syscall is 2 on Linux x86-64, while it is 5 on FreeBSD.
50%UnverifiedThe error code EAGAIN has a value of 11 on Linux and 35 on FreeBSD.
