UBUNTU-CVE-2022-49020

In the Linux kernel, the following vulnerability has been resolved: net/9p: Fix a potential socket leak in p9socketopen Both p9fdcreatetcp and p9fdcreateunix will call p9socketopen. If the creation of p9transfd fails, p9fdcreatetcp and p9fdcreateunix will return an error directly instead of...

CVE-2022-49020

In CVE-2022-49020, the Linux kernel’s net/9p code has a socket leak: p9_fd_create_tcp() and p9_fd_create_unix() call p9_socket_open(), and if p9_trans_fd creation fails they return an error without releasing the socket. The root cause is failure to sock_release() the socket, which this patch fixe...

CVE-2024-49946

CVE-2024-49946 affects the Linux kernel PPP stack. The issue arises in ppp_channel_bridge_input() when packets are backlogged to a socket owned by a user process and the code path can call sk_backlog_rcv()/__release_sock()/release_sock() in process context. This creates an inconsistent lock state...
