Technical Summary
CVE-2026-14758 describes an integer overflow vulnerability in radareorg radare2 affecting versions 6.1.0 to 6.1.6. The issue is located in the cmd_anal_opcode function within the hexpairs Parser component (file libr/core/cmd_anal.inc.c). Exploitation requires local access and no user interaction. The vulnerability can cause integer overflow, potentially leading to incorrect program behavior or crashes. A patch identified by commit 84e773986e7e5bb30453a9384f498ec0ccc9d0a9 has been made available to fix the issue.
Potential Impact
The vulnerability allows a local attacker with low privileges to trigger an integer overflow in radare2, which may cause unexpected behavior or crashes. The CVSS score of 4.8 indicates a medium severity impact. There is no indication of remote exploitation or privilege escalation. No known exploits in the wild have been reported.
Mitigation Recommendations
A patch identified by commit 84e773986e7e5bb30453a9384f498ec0ccc9d0a9 is available and should be applied to affected versions 6.1.0 through 6.1.6 to remediate this integer overflow vulnerability.
