CVE-2025-37790

The CVE-2025-37790 issue concerns the Linux kernel: specifically the net: mctp: Set SOCK_RCU_FREE path where a socket could disappear during a Bind lookup that runs under RCU. The vulnerability arises from the Bind lookup performing operations under RCU, potentially leading to use-after-free scen...

CVE-2025-37756 net: tls: explicitly disallow disconnect

In the Linux kernel, the following vulnerability has been resolved: net: tls: explicitly disallow disconnect syzbot discovered that it can disconnect a TLS socket and then run into all sort of unexpected corner cases. I have a vague recollection of Eric pointing this out to us a long time ago...

CVE-2025-37756

CVE-2025-37756 relates to the Linux kernel TLS stack. The vulnerability arises from allowing a TLS socket disconnect, which can trigger unexpected corner cases in the TLS receive path. The fix is a kernel patch that explicitly disallows disconnect in net/tls, reducing the risk of abusive disconne...

CVE-2025-23143

CVE-2025-23143 is a Linux kernel issue where unloading a module (e.g., CIFS/NFS) can race with a TCP socket still alive, leading to a NULL pointer dereference in lockdep when hlock_class() is called after the module is gone. The root cause is that CIFS assigns a different lock class to the socket...
