发布于3月6日3月6日 Members Huawei EulerOS: CVE-2022-48757: kernel security update Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 06/20/2024 Created 10/09/2024 Added 10/08/2024 Modified 01/15/2025 Description In the Linux kernel, the following vulnerability has been resolved: net: fix information leakage in /proc/net/ptype In one net namespace, after creating a packet socket without binding it to a device, users in other net namespaces can observe the new `packet_type` added by this packet socket by reading `/proc/net/ptype` file. This is minor information leakage as packet socket is namespace aware. Add a net pointer in `packet_type` to keep the net namespace of of corresponding packet socket. In `ptype_seq_show`, this net pointer must be checked when it is not NULL.
