Vulnerability from fkie_nvd - Published: 2025-02-26 07:01 - Updated: 2026-06-17 05:17
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: tty: goldfish: Use tty_port_destroy() to destroy port In goldfish_tty_probe(), the port initialized through tty_port_init() should be destroyed in error paths.In goldfish_tty_remove(), qtty->port also should be destroyed or else might leak resources. Fix the above by calling tty_port_destroy().
