CVE-2025-66864 [HIGH] CWE-476 binutils: NULL pointer dereference in d_print_comp_inner() in cp-demangle.c
binutils: NULL pointer dereference in d_print_comp_inner() in cp-demangle.c
An issue was discovered in function d_print_comp_inner in file cp-demangle.c in BinUtils 2.26 allows attackers to cause a denial of service via crafted PE file.
A flaw was found in binutils. Processing a specially crafted PE file with cxxfilt can trigger a NULL pointer dereference in the d_print_comp_inner function in the cp-demangle.c file, causing a crash and resulting in a denial of service.
Statement: This issue is classified with a low severity primarily because binutils is not typically exposed to untrusted inputs in most environments, limiting the possibility of exploitation. Additionally, this NULL pointer dereference is only triggered during the parsing of a specially crafted file, requiring an attacker
