In the Linux kernel, the following vulnerability has been resolved:net: fix information leakage in /proc/net/ptypeIn one net namespace, after creating a packet socket without bindingit to a device, users in other net namespaces can observe the newpacket_type added by this packet socket by reading /proc/net/ptypefile. This is minor information leakage as packet socket isnamespace aware.Add a net pointer in packet_type to keep the net namespace ofof corresponding packet socket. In ptype_seq_show, this net pointermust be checked when it is not NULL.

CVE-2022-48757

影响性分析说明：
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.
