Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/9p: Fix a potential socket leak in p9_socket_open<br /> <br /> Both p9_fd_create_tcp() and p9_fd_create_unix() will call<br /> p9_socket_open(). If the creation of p9_trans_fd fails,<br /> p9_fd_create_tcp() and p9_fd_create_unix() will return an<br /> error directly instead of releasing the cscoket, which will<br /> result in a socket leak.<br /> <br /> This patch adds sock_release() to fix the leak issue.
