CVE-2026-8695

radare2 6.1.5 contains a use-after-free vulnerability in the gdbrthreadslist() function that allows remote attackers to trigger memory corruption by sending a valid qfThreadInfo response followed by a malformed qsThreadInfo response. Attackers can exploit this vulnerability through GDB remote debugging to cause a denial of service or potentially achieve code execution by manipulating thread list processing.
