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. The Linux kernel CVE team has assigned CVE-2026-64011 to this issue.

Affected files ============== The file(s) affected by this issue are: net/nfc/llcp_sock.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/89ba026747019ee643d29407435ddc118e6ca908 https://git.kernel.org/stable/c/fb29f6bbe433f3decad227588809636c25f2a287 https://git.kernel.org/stable/c/2dfdaaf7d933b676124aadec6698825e95f94fe9 https://git.kernel.org/stable/c/e00f50f8697724a6f1d2d35744c1332c9912dac5 https://git.kernel.org/stable/c/cdc17e09a636c7f936f771902535a7515a7608fc https://git.kernel.org/stable/c/912ebc49d4406a17fe73e5671d674fbc2f6b2634 https://git.kernel.org/stable/c/bc421d0826dedbba37580a25405eafb599e76d42 https://git.kernel.org/stable/c/f4268b466190dae95a7585f69b4f1f8ad097632c
