Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A issue in the Linux kernel has been resolved, related to the goldfish tty driver. In the goldfish tty probe() function, the port initialized through tty port init() should be destroyed in error paths to prevent resource leaks. Similarly, in goldfish tty remove(), the qtty->port should be destroyed. The fix involves calling tty port destroy() to properly clean up resources.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
