CVE-2022-49020

  3. CVE-2022-49020
In 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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/9p: Se soluciona una posible fuga de socket en p9_socket_open Tanto p9_fd_create_tcp() como p9_fd_create_unix() llamarán a p9_socket_open(). Si la creación de p9_trans_fd fallo, p9_fd_create_tcp() y p9_fd_create_unix() devolverán un error directamente en lugar de liberar el cscoket, lo que provocará una fuga de socket. Este parche agrega sock_release() para solucionar el problema de la fuga.
