| Subject: CVE-2022-49399: tty: goldfish: Use tty_port_destroy() to destroy port |
| |
| Description |
| =========== |
| |
| 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(). |
| |
| The Linux kernel CVE team has assigned CVE-2022-49399 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
