CVE-2026-64011 Details
Description
In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: Fix use-after-free in llcp_sock_release() llcp_sock_release() unconditionally unlinks the socket from the local sockets list. However, if the socket is still in connecting state, it is on the connecting list. Fix this by checking the socket state and unlinking from the correct list.
A use-after-free vulnerability has been identified in the Linux kernel's NFC LLCP socket handling. The issue arises in the `llcp_sock_release()` function, which improperly unlinks sockets from the local sockets list without considering their connection state. This oversight can lead to a use-after-free condition, as sockets in the connecting state are not correctly managed. The vulnerability affects the Linux kernel stable group.
Users can upgrade to the latest version of the Linux kernel stable branch, where this vulnerability has been addressed.
