No EPSS score is available and the issue is not listed in the CISA KEV catalog. The attack vector is inferred to be local: an attacker must be able to supply a malicious PDB file to radare2. If the tool processes user\u2011controlled PDB data, the attacker can execute arbitrary r2 commands, potentially escalating to system\u2011level commands.
