Описание
ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-e69dbd4619e7.
A vulnerability was discovered in the Linux kernel's AF_IEEE802154 networking module where permissions checks are not enforced. This can allow an unprivileged user to create raw sockets for this protocol leading to the potential for data leaks or system unavailability.
Отчет
This flaw is rated as moderate; there are no known exploits using this mechanism as an attack surface against the system affected by this bug.
