CVE-2026-52753Public exploit

Process crash via unbounded Rust demangling

Published Jun 10, 2026 · Updated Jun 10, 2026

Out-of-memory allocation in Ghidra before 12.0.3 allows attackers to crash the application by analyzing a crafted binary. The GPL/DemanglerGnu rust_demangle path sends malformed Rust v0 symbol expansion to str_buf_reserve, which doubles the output buffer without a maximum-size check. A user must open or analyze the attacker-supplied binary; the resulting resource exhaustion interrupts that Ghidra process without reported data disclosure or modification.
