This vulnerability involves a use-after-free condition in the ssh component of OpenSSH prior to version 10.5. The flaw is triggered by a specific pair of concurrent remote-forwarding operations that cause the program to access memory that has already been freed (realloc data). This can potentially lead to memory corruption or other unintended behavior. The CVSS vector indicates that the attack requires network access with high attack complexity and no privileges or user interaction, resulting in low confidentiality and integrity impacts and no availability impact.

The vulnerability could allow an unauthenticated remote attacker to cause a use-after-free condition, potentially leading to memory corruption. The impact is rated as medium with limited confidentiality and integrity effects and no impact on availability. There are no known exploits in the wild at this time.
