unix domain sockets

About this tag
Unix domain sockets (AF_UNIX) are a foundational inter-process communication (IPC) mechanism on Unix and Linux systems. Recent discussions on WindowsForum.com cover a Linux kernel vulnerability, CVE-2023-6531, which involves a use-after-free bug in the AF_UNIX garbage collector. This flaw can lead to system crashes or potential memory corruption. While Windows does not natively use Unix domain sockets, Windows Subsystem for Linux (WSL) and cross-platform applications may rely on them. The tag content focuses on security implications, kernel internals, and the importance of patching affected Linux systems.

    Linux Kernel CVE-2023-6531: AF_UNIX Garbage Collector Use-After-Free

    A subtle race in the Linux kernel’s Unix-domain socket garbage collector can let the kernel free socket buffers (skbs) while another path still holds a pointer to them, producing a classic use‑after‑free (UAF) that can crash or destabilize systems and — in theory — open the door to more serious...
