GHSA-495C-G5J5-WG9W
Vulnerability from github – Published: 2024-10-21 21:30 – Updated: 2024-10-24 21:31In the Linux kernel, the following vulnerability has been resolved:
net/9p: Fix a potential socket leak in p9_socket_open
Both p9_fd_create_tcp() and p9_fd_create_unix() will call p9_socket_open(). If the creation of p9_trans_fd fails, p9_fd_create_tcp() and p9_fd_create_unix() will return an error directly instead of releasing the cscoket, which will result in a socket leak.
This patch adds sock_release() to fix the leak issue.
