Vulnerability details

The vulnerability allows a remote user to execute arbitrary code or cause a denial of service.

The vulnerability exists due to out-of-bounds write in the udiv128 simplification helper when processing a loaded binary that contains a compiler-emitted divide-by-constant pattern during decompilation. A remote user can provide a specially crafted binary to execute arbitrary code or cause a denial of service.

The issue is reachable from the RuleDivOpt simplification rule in the Ghidra C++ decompiler, and successful exploitation depends on stack layout and stack-protector configuration.
