determining impact of vulnerability CVE-2022-27943 in libiberty/rust-demangle.c

[fus@xxxxxxxxxxxxxx]

The above mentioned CVE 
(https://nvd.nist.gov/vuln/detail/CVE-2022-27943) just specifies GNU GCC 
11.2 to be affected, but fails to eplicitly specify that previous 
versions are not affected. Does this CVE only affect exactly GCC version 
11.2?

And I would also like to know how I can determine whether or not I will 
be eposed to this vulnerability when using an affected version. Is the 
rust demangler used internally by any C/C++ tools or will I only be 
affected when compiling rust programs?

Regards
Frank
