CVE-2022-49020 – net/9p: Fix a potential socket leak in p9_socket_open
https://notcve.org/view.php?id=CVE-2022-49020
21 Oct 2024 — 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. • https://git.kernel.org/stable/c/6b18662e239a032f908b7f6e164bdf7e2e0a32c9 •

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new() As comment of pci_get_domain_bus_and_slot() says, it returns a pci device with refcount increment, when finish using it, the caller must decrement the reference count by calling pci_dev_put(). So call it after using to avoid refcount leak. A counting logic flaw exists in the Linux kernel.
