Authorization Bypass

linux kernel is vulnerable to authorization bypass. A missing CAPNETRAW check in the NFC socket creation in net/nfc/rawsock.c allows local attackers to bypass security mechanisms and create raw sockets...

kernel: unprivileged users able to create RAW sockets in AF_IEEE802154 network protocol

A vulnerability was discovered in the Linux kernel's AFIEEE802154 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...

kernel: unprivileged users able to create RAW sockets in AF_ISDN network protocol

A vulnerability was found in the Linux kernel’s implementation of the AFISDN protocol, which does not enforce the CAPNETRAW capability. This flaw can allow unprivileged users to create a raw socket for this protocol. This could further allow the user to control the availability of an existing ISD...
