The original title is: "GhostLock: Uncovering the 15-Year-Old Linux Stack Use-After-Free Vulnerability"

Short summary

GhostLock (CVE-2023-1228) exposed a 15-year-old stack use-after-free vulnerability in Linux kernel tty_ldisc handling dating back to 2008. The exploit chain leverages race conditions in reference counting to pivot the stack and escalate privileges. Linux patched this with atomic reference counting, stack canary improvements, and KASAN runtime detection, offering lessons for memory-safe systems programming.
