lgc.c in Lua 5.4.0 mishandles the interaction between barriers and the sweep phase, leading to a memory access violation involving collectgarbage.

ldebug.c in Lua 5.4.0 allows a negation overflow and segmentation fault in getlocal and setlocal, as demonstrated by getlocal(3,2^31).

In Lua 5.4.3, an erroneous finalizer called during a tail call leads to a heap-based buffer over-read.

Stack overflow in luaresume of ldo.c in Lua Interpreter 5.1.0~5.4.4 allows attackers to perform a Denial of Service via a crafted script file.

ldebug.c in Lua 5.4.0 attempts to access debug information via the line hook of a stripped function, leading to a NULL pointer dereference.

Lua through 5.4.0 allows a stack redzone cross in luaOpushvfstring because a protection mechanism wrongly calls luaDcallnoyield twice in a row.

Lua through 5.4.0 mishandles the interaction between stack resizes and garbage collection, leading to a heap-based buffer overflow, heap-based buffer over-read, or use-after-free.
