OpenBSD Project reports:

+
+

+ ssh-agent(1): fixed a double-free memory corruption that was + introduced in OpenSSH 8.2 . We treat all such memory faults as + potentially exploitable. This bug could be reached by an attacker + with access to the agent socket. +

+

+ On modern operating systems where the OS can provide information + about the user identity connected to a socket, OpenSSH ssh-agent + and sshd limit agent socket access only to the originating user + and root. Additional mitigation may be afforded by the system's + malloc(3)/free(3) implementation, if it detects double-free + conditions. +

+

+ The most likely scenario for exploitation is a user forwarding an + agent either to an account shared with a malicious user or to a + host with an attacker holding root access. +
