MITRE ATT&CK

2 techniques across 2 tactics: Execution, Privilege Escalation

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Impact

Successful exploitation can lead to arbitrary code execution, denial of service, or privilege escalation depending on the memory layout and protections in place. With a CVSS score of 2.5 (LOW), this represents a low risk.

Exploit ScenarioDerived

An attacker sends an oversized input to a vulnerable function, overwriting the return address on the stack to redirect execution to attacker-controlled shellcode.

Monitor Track and reassess. Why: LOW severity (CVSS 0.1-3.9).

AnalysisAIv1 – Mar 14, 2026

A vulnerability was found in Radare2 5.9.9. It has been classified as problematic. Affected is the function r_cons_pal_init in the library /libr/cons/pal.c of the component radiff2. The manipulation of the argument -T leads to memory corruption. An attack has to be approached locally. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The name of the patch is 5705d99cc1f23f36f9a84aab26d1724010b97798. It is recommended to apply a patch to fix this issue. The documentation explains that the parameter -T is experimental and "crashy". Further analysis has shown "the race is not a real problem unless you use asan". A new warning has been added.

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
