Summary

libiberty/rust-demangle.c in GNU GCC 11.2 allows stack consumption in demangle_const, as demonstrated by nm-new. The flaw can lead to stack exhaustion when processing crafted input.

Risk Assessment

An attacker can supply a malicious file to crash tools based on libiberty, impacting availability. The risk affects environments processing untrusted binaries.
