About this tag
CVE-2023-6531 is a use-after-free vulnerability in the Linux kernel's AF_UNIX garbage collector, specifically within the Unix-domain socket subsystem. The flaw arises from a race condition where socket buffers (skbs) can be freed while another execution path still holds a reference, leading to potential system crashes or memory corruption. This vulnerability was publicly disclosed on January 21, 2024, and affects Linux systems using Unix domain sockets for inter-process communication. Discussions on WindowsForum.com cover the technical details of the race condition, the affected kernel components, and the potential security implications for enterprise and server environments running Linux.

    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...
