Published Jan 23, 2026
·
Updated

In the Linux kernel, the following vulnerability has been resolved: net/handshake: restore destructor on submit failure handshakereqsubmit() replaces sk->skdestruct but never restores it when submission fails before the request is hashed. handshakeskdestruct() then returns early and the original destructor never runs, leaking the socket. Restore skdestruct on the error path.

Frequently Asked Questions

1

Which Ubuntu kernel packages are listed as affected?

The listed packages are ubuntu/linux-riscv, ubuntu/linux-realtime, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-azure-fde, ubuntu/linux-hwe-edge, ubuntu/linux-gke, and ubuntu/linux-gkeop.

2

What conditions lead to the resource leak?

The leak occurs when handshake_req_submit() replaces the socket destructor and submission then fails before the request is hashed. The replacement destructor returns early, preventing the original socket destructor from running and leaving the socket leaked.

3

What is the impact described for this issue?

The described impact is a socket resource leak. The supplied severity vector indicates network attack vector, low attack complexity, no privileges or user interaction required, and availability impact limited to the vulnerable component.
