Analysis
LuaJIT through 2.1 and OpenRusty luajit2 before v2.1-20240314 have an unsinking of IR_FSTORE for NULL metatable, which leads to Denial of Service (DoS).
Technical Context

Affected Products
Affected products: Luajit Luajit
Remediation
A vendor patch is available — apply it immediately. Add NULL checks before pointer dereference operations. Use static analysis to identify potential NULL pointer issues. Enable compiler warnings.
